Split diacritics from letters

[honguyenminh]

Currently letters with diacritics count as 1 single character, and are only shown as correct if the full character is present.
Most input methods, however, usually input them separately, not at the same time. For example, in Vietnamese, to type cánh, you would type canh, and then s to add the diacritic to make cánh.
Monkeytype will show á as incorrect when you type canh first, which can cause confusion whether you typed the a correctly or not.
How about we split the diacritics from the letter? If only diacritics are missing, show only them as missing, not mark the entire character as incorrect.
