The CSS WG needs advice on initial letter styling in non-Latin scripts, ie. enlarged letters or syllables at the start of a paragraph like those shown in the picture. Most of the current content of the recently published Working Draft, CSS Inline Layout Module Level 3 is about styling of initial letters, but the editors need to ensure that they have covered the needs of users of non-Latin scripts.
The spec currently describes drop, sunken and raised initial characters, and allows you to manipulate them using the initial-letter and the initial-letter-align properties. You can apply those properties to text selected by ::first-letter, or to the first child of a block (such as a span).
The editors are looking for
any examples of drop initials in non-western scripts, especially Arabic and Indic scripts.
I have scanned some examples from newspapers (so, not high quality print).
In the section about initial-letter-align the spec says:
Input from those knowledgeable about non-Western typographic traditions would be very helpful in describing the appropriate alignments. More values may be required for this property.
