Hey! I have the exact same problem, I use a QWERTY U.S. international keyboard on an iPad and usually type accented letters by typing first the accent, then the letter:
’ then e => é
` then e => è
" then e => ë
^ then e => ê
The problem occurs for the symbols ’ and " when the accented letter is at the beginning of a word (except if it’s the first letter of the paragraph). For instance writing “Test [accent then e]” results in:
Test ‘é’
Test è
Test “ë”
Test ê
Hope this helps! Any help would be appreciated.
Edit: I believe this to be a bug. Maybe this should be posted in a the bug section of the forum?
