Some characters can't be typed by using diacritic keys
Characters with diacritics that can't be typed by using diacritic keys are: ễ,ể,ẫ,ẩ,ỗ,ổ (e.g. instead of showing 'ẩ' in 'a' key, it will showing 'ả' when activating ̂(circumflex) and ̉(hook above) ). Additionally, it can't type some standalone diacritics such as ̉ (hook above) and ̣(dot below) . Those characters are used in my language so please fix this bug. Thank you.
P.S. please ignore my previous issue it was accidentally created
The first issue about wrong output character when using multiple diaratics, I seems can't replicate the issue (you may press keys in wrong order?)
The second issue, I'm not sure, I have seen 6 diaratics of Vietnamese in Unicode, but they are used to combining with base letters (when using Compose Unicode, not Precompose Unicode encoding)
Sorry for the slow reply. Could you provide a table of the letters with diacritics that you want ?
@SweetSea-ButImNotSweet ễ is definitely a unicode character. Support for composing unicode diacritics has been added recently.
