Almost correct when typing in Vietnamese
When I type Vietnamese words with tone marks Duo always says "Almost Correct" It always happens with tone marks, nothing else. example: http://imgur.com/a/yHtlB
I am using a Vietnamese keyboard on Debian Linux.
Anybody have a solution?
I also have the same problem, but i just ignore it. Here is a link that may get rid of that though: https://www.duolingo.com/comment/17996305/Diacritics-in-Vietnamese
For linux, you need to select the keyboard layout tcvn (m17n) not the 'Vietnamese' layout. You may need to install iBus. Good luck!
It does similar things sometimes on iOS.
On the technical side of things, there are actually different letters (as represented in computer code) that look absolutely the same or very similar as to be interpreted as "the same letter" by humans.
I presume that's the source of these errors, and if the case, the only solution would be to either ensure you're inputting the exact same code that's accepted by Duolingo, or for Duolingo to also accept the code you're inputting.
