According to this page 
(http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/RIFF.html#Info) 
it is possible
to add language information ("IAS1" (first language) to "IAS9" (ninth 
language)) to RIFF tagged files (as RIFF Info Tags).
Programs such as VLC media player or MediaInfo can properly read and 
display this information. Allowing to set this tags
with the -metadata option while encoding, would simplify the process.
