I am compiling these notes as I explore the Bengali script as used for Bengali. They may be updated from time to time.
The page lists the Unicode characters used to represent Bengali text, and briefly describes their use. It starts with short notes on general script features and discussions about which Unicode characters are most appropriate when there is a choice.
For more detailed information, especially about the history and phonology of Bengali, follow the links in the text and at the bottom of the page. You can also click on the symbols in the next section to jump to a description of that character.
To view this page as intended, you should download the (free) Solaiman Lipi font from the Web (see the side bar).

Bengali has its own script, called বাংলা baɱla in the Bengali language.
The script is an abugida. This is characterised by consonant characters that include an inherent vowel sound. The inherent vowel can be overridden using vowel signs appended to the character. There are also independent vowel signs to represent vowels that are not preceded by consonants. The syllable is the unit for various aspects of the behaviour of the script.
The alphabet is split into vowels and consonants. With one exception (ɔ-kar), each vowel is represented by an independent version and a combining vowel sign, shown one above the other.
The pronunciation of a vowel can be affected by the vowel in the following syllable. Radice provides the following table, though this is a simplification and there are many exceptions.
| Followed by i or u | Followed by ɔ, o, e or a |
|---|---|
| o → u | o → ɔ |
| ɔ → o | u → o |
| e → i | e → æ |
| æ → e | i → e |
For example, ʃona becomes ʃuni, dækha becomes dekhi, etc. This sometimes accounts for the pronunciation of the inherent vowel.
The inherent vowel, unlike Hindi, is [ɔ] or [o]. (And sometimes halfway between these two, when influenced by surrounding sounds.) Bengalis are not always aware of these sound differences - thinking of this as one sound.
Note that there is also a vowel pronounced [o]. This can lead to inconsistent spellings, eg. bhalo, good, well, can be spelled either ভালো or ভাল. Verb forms tend to be particularly inconsistent, sometimes basing the rationale on what looks good in a particular context.
The rules for determining the sound of the inherent vowel are not simple. Partly it is a question of vowel harmony. The following two tendencies can help:
In words with inherent vowels in two consecutive syllables, the sound will usually be ɔ/o, not o/ɔ, eg. গরম gɔrôm, hot.
The inherent vowel is always pronounced ɔ in words that end with a conjunct consonant and pronounce the vowel.
The inherent vowel is pronounced at the end of some words and not others, eg. গরম gɔrôm, hot vs. গড়ান gɔɽanô, to roll . There is no real way to tell when it is pronounced and when not in this position, except that it is usually pronounced following a word-final conjunct, eg. যুদ্ধ y̌uddhô war. When pronounced in this position, the sound is usually [o] .
Refs: Radice 3, 7-8, 21, 148; Daniels 400
Some vowel signs can form ligatures with a preceding base consonant in certain contexts, but do not ligate in others (eg. newspapers and modern typefaces). Both forms are equivalent in every way but visually.
The default behaviour of a given font can be modified using the zero-width joiner and zero-width non-joiner characters, eg. গু vs. গু.
Refs: Unicode 313-314
The absence of vowels between consonants can be represented by
Like other scripts, rɔ is displayed in a non-standard way in consonant clusters. A syllable initial rɔ is displayed as a mark to the top right of the cluster, and a trailing rɔ is typically displayed as a wavy line below the other consonants.
Bengali also has a particular way of representing a cluster-final [j] semi-vowel. This is typically represented using the full form of the preceding consonant followed by sign y̌ɔ-phɔla .
Consonant clusters are not always represented as conjuncts. Grammatical suffixes and endings are written without, eg. খাননা khanna, which is present tense form khan plus negative suffix na; করছ kôrchô, which is stem kôr from kôra plus present continuous ending chô.
Nasals in conjuncts tend to follow phonological rules. Velar consonants (k, kh, g, etc) take ঙ ñɔ, palatal consonant (c, ch, ..) combine with ঞ ñɔ, retroflex take ণ ɳɔ, dental ন nɔ, and labial ম mɔ.
The danda (found in the Devanagari block) is used for sentence final punctuation. I haven't seen much evidence for the use of the double danda.
Western punctuation, such as commas, semicolons, colons, quotation marks and hyphens are also used quite commonly.
bisɔr͟gô ঃ 0983 BENGALI SIGN VISARGA is sometimes used to mark initial abbreviation.
Refs: Bhattacharya
The Bengali character block in Unicode provides 3 precomposed characters that are decomposed in Normalization Form C. The NFC form should be used.
The Bengali block also has code points that enable you to split vowel signs that circumvent the base into two parts; the single code point should be used. (If you do use the two code points, they must be both input after the base, and in the correct order.)

Bengali consonant, ɖɔ
[ɖ]
Transcriptions. ISO 15919 ḍ; here ɖ
With nukta. [ɽ] with 09BC BENGALI SIGN NUKTA ড় is a retroflex flap. Curl tongue as if for [ɖ] but before making contact with the alveolar ridge flap the tongue down smartly to make audible contact with the bottom of the mouth.
In Sanskrit this was merely an allophone of ড between vowels. The distinguishing dot was added to the Bengali script in the 19th century. Now it is regarded as a letter of the alphabet.
The precomposed character 09DC BENGALI LETTER RRA is equivalent to this decomposed sequence, but the decomposed sequence is produced by NFC, so should be used in preference.

With nukta. ɽ or ɽh with 09BC BENGALI SIGN NUKTA ঢ়. Theoretically this is the aspirated version of ɽɔ, but in practice not normally pronounced with aspiration, although it occasionally may be, as in রাঢ়. A very rare letter, the only common word in which it appears is the Bengali month আষাঢ় aʂaɽh, (June-July).
The precomposed character 09DD BENGALI LETTER RHA is equivalent to this decomposed sequence, but the decomposed sequence is produced by NFC, and so should be used in preference.

Transcriptions: ISO 15919 t; here t
Unusual conjunct pronunciations:
ত্ম tm, tː

Special vowel combinations: The syllable ntu can be written in modern typefaces with the u below the n͟t conjunct, but in older print a special arrangement incorporates all three sounds together, eg. কিন্তু kin͟tu, but.
The combination tru is represented by ত্রু.
Khanda ta In some words a tɔ that has no following inherent or other vowel may have a shape like ৎ. It is called খণ্ড ত khɔɳ͟ɖô tɔ. It either comes at the end of words, eg. হঠাৎ hɔʈhaṯ (suddenly), or before a consonant that doesn't naturally combine with tɔ, eg. উৎসব uṯsɔb (festival). Many such words, however, use ত. It's not possible to say which will be used.
Unicode 4.1 added a separate character for khɔɳɖȏ tɔ, 09CE BENGALI LETTER KHANDA TA, which should be used when this shape is needed. (This replaces a previous approach that required the use of 09A4: BENGALI LETTER TA + 09CD: BENGALI SIGN VIRAMA + 200D: ZERO WIDTH JOINER.)

ʤ at the beginning of a word. In Bangladesh this can sound more like z, especially in words of Perso-Arabic origin.

Conjuncts formed with y̌ɔ-phɔla are unusual because the y̌ɔ-phɔla is reduced but not the preceding base, eg. ক + য = ক্য. This is the default form when y̌ɔ-phɔla follows 09CD BENGALI SIGN VIRAMA.
An exception to the rule for shaping of y̌ɔ-phɔla can occur when rɔ is the first letter in the conjunct. This combination is typically rendered using the reph and a full ɔn͟tɔḥs͟thô y̌ɔ, ie. র্য, but may be rendered using the ordinary y̌ɔ-phɔla form after a full form rɔ, ie.
র + য = র্য or র্য
Unicode 4.01 clarified how to address this. Use 200C: ZERO WIDTH NON-JOINER to consistently produce the desired form, as shown below:
র + virama + য = র্য
র + zwnj + virama + য = র্য
y̌ɔ-phɔla can also be used after independent vowels though this doesn't appear to be common.
With nukta. When followed by a 09BC BENGALI SIGN NUKTA য় this becomes ɔn͟tɔḥs͟thô ɔ অন্তঃস্থ য় and is used for the semi-vowel.
j between i...e, a...u, or e...e.
e after another vowel, particularly after ɔ, a or o, eg. ভয় bʰɔe (fear).
w (light, like French 'oui') between o...a , eg. খওরা kʰaowa (to eat, drink).
Sometimes it is scarcely pronounced at all, eg. মেরে mee (girl, woman).
The dot was added in the 19th century, to contrast this with ɔn͟tɔḥs͟thô y̌ɔ.
The precomposed character 09DF BENGALI LETTER YYA is equivalent to this decomposed sequence, but the decomposed sequence is produced by NFC, so should be used in preference.

Conjunct appearance. When it occurs as the second element in a conjunct it is typically written as a wavy horizontal line, eg. ব + র = ব্র. This mark is called rɔ-phɔla র-ফলা.
When it occurs as the first element in a conjunct it is typically written as a diagonal stroke above the consonant that follows it, eg. র + য = র্য. This mark is called reph রেফ.
Unusual vowel combinations. To avoid clashing with the dot, the vowel sign for u appears to the side when attached to rɔ, ie. রু. Similarly, the vowel sign for ū appears to the side when attached to rɔ, ie. রূ.

Notes from the Unicode standard:
• a dead consonant form of ta, without implicit vowel, used in some sequences
Bengali consonant, khɔɳɖȏ tɔ খণ্ড ত্

U+0982 BENGALI SIGN ANUSVARA
Bengali consonant, ônus͟var অনুস্বার or ônus͟vôr অনুস্বর

Never has a vowel sign.
Sometimes spelling is inconsistent, especially when this or ঙ are used in a conjunct, eg. সাঙঘাতিক or সাংঘাতিক (terrible, tremendous); রঙ or রং (colour).
In certain words the spelling is fixed, however. বাংলা is one such word. However, since this cannot support vowel signs, the word for Bengali nation (rather than language) has to be spelled with ঙ, ie. বাঙালী baŋalī.
In the sequence of characters, this should occur after any combining vowel sign associated with the same syllable.

U+09CD BENGALI SIGN VIRAMA
Notes from the Unicode standard:
= hasant (Bengali term for halant)
Bengali mark, viram বিসর্গ
Used between two consonants in a conjunct, in which case it is usually invisible, but sometimes not. Where not, it is usually because the font doesn't have a particular conjunct ligature, but it may also be visible in places where the phonology is unusual, eg. ফ্ল্যাট (flat); লান্চ (lunch) (though these may also be spelled with conjuncts, eg. ফ্ল্যাট). It is also quite common to see উদ্যাপন to distinguish it from words like উদ্যান. These words are etymologically related, but distinct phonetically.
This character should always be positioned before any combining vowel mark in memory.
