This latest picker includes characters used for writing Vietnamese. Characters are taken from various Latin Unicode blocks.
Tones are separated from base characters in the selection area, but the output you create is always fully precomposed. If you copy and paste text into the output area, you can normalize the Vietnamese text as NFC by selecting the tab below. The Vietnamese text in the output area is also normalized when you select one of the transcription tabs.
The tabs IPA N and IPA S tabs provide a basic, mostly phonemic-level, transcription of the pronunciation. N means North Vietnamese, S is for South. The sources I used for this varied a great deal, particularly in the choice of symbols to represent vowels. There are also more than two main dialects. So this is a synthesis and a rough guide. Some rare vowel combinations may be missing, although I have covered quite a number.
There are a large number of UVN fonts – so many that I didn’t know which ones to pick for the font pulldown. I chose the two that show up on Alan Wood’s page. If you think certain others are so common that they ought to be there, please let me know.
Enjoy.
