On the very first page that one sees in the F10 release notes, <http://docs.fedoraproject.org/release-notes/f10/>, the newbie is presented with a list of cryptic language designations. There is plenty of room to spell the language names out (and possibly postfix the designator in parentheses, e.g. Russian (ru). For many, these designators are meaningless and may turn them away from Fedora before they ever get past page 1 because they can't find their language. Given all the work put into international translation, it seems a shame to not make this page "user friendly".
I used to spell these language names out in their native language and, if I recall correctly, it was criticized as a bug because the names would generate erroneous "missing character" boxes for people without the required fonts installed. It would be wrong, in my opinion, to either spell these out in English only, or to spell out only those names we can represent with a Latin character set.
