Comment 24 for bug 651586

My point: It is difficult or even impossible for people to add a new spellcheck in Chromium.

It does not take short period for a language to collect enough statistics to build a spellchecker. At least it takes the following steps:
1. Well documented.
2. Revival it for using it more.
3. Have enough articles to generate statistics, or have an organization to check every text produced and justified about the spelling / orthography.
4. Generating the .dic / .aff

I read from Wikipedia and Evertype.com that Ireland that nearly a hundred years to revival the written Irish Gaelics. And now, the aboriginal Taiwanese started to have textbook in their own around ten years ago. It is about the time the first generation of kids educated in their aboriginal language are capable to analyse their native tongue. I see studies of their languages as well as language tools emerging.
