Cyrillic letters may appear not only in Russian just as French and 
Spanish use Latin script. So language detection based on symbol code 
points works only for distinct enough languages. Explicit markup may 
still be necessary to switch hyphenation rules, dash styles, etc.

I have a couple of bookmarks for language detection libraries (not for 
Emacs), but I am unsure if they may work for texts containing fragments 
written in different languages.
