Comment 1 for bug 656690

Hello Phương, your English is wonderful! The characters (ả, ẻ, ủ, ẽ, ớ, ờ, ...) that you have mentioned as rendering differently, being drawn from another font. These characters are in the "Latin Extended Additional" block which the Ubuntu Font Family does not currently support; you can hopefully find all of the characters them in the following PDF:

Currently the "Latin Extended Additional" block is scheduled for doing later, and probably for expansion by the community. At the moment the focus is on trying to get Monospace, Arabic and Hebrew in progress. (Making a font takes a *very* long time, and it is not possible to do everything and all languages at once. Instead we need to do one language/script at a time).

Please could you ask other people to vote on this bug report (Click "Affects me too...") if they are also Vietnamese users: this will help to judge which scripts and languages to focus on, in which order. In the mean-time I've milestoned this against the "latin-extended-additional" milestone, which you should be able to keep track of.

It would be very useful if you could give a full (and complete) list of *all* of the characters (with *all* their accents) that are needed to get Vietnamese fully covered, when the time comes.
