Belarusian Latin Damned Lies

["Ihar Hrachyshka" <ihar hrachyshka gmail com>]

Hello!
I translated Damned Lies (be latin po), but I can't see the results of
the work in my browser. It's because IANA code for Belarusian Latin
language is be-Latn, not be latin  How can we map be latin to standard
be-Latn code on the Web?
Thanks.
