It is not often that I find I cannot see the characters in a text. Today I installed a font for the script that is used for all the Yi languages.
This font is provided by SIL, it is available under the Open Font License. I came to install it because there is a Wikipedia in the Sichuan Yi language, its main page indicates in English that it is now at the Incubator. It is one of the languages that is not yet supported in Betawiki.. It will need a person to request it to make it so.
The list of Wikipedias proves to be incorrect because several Wikipedias have been closed. This is not reflected on the list.
