It is a known limitation of most LaTeX mathbb fonts to only support
uppercase Latin letters.
Exceptions include STIX fonts, some Unicode math fonts
and the packages fourier, fouriernc, and mathbbol.
The "symbols.pdf" document may also help
try
texdoc symbols
on the command line if you have TeXLive.
