What this patch appears to do, at least based on my testing, is to
output Braille in the proper BRF format, which uses upper-case letters
for the letter symbols, and uses a few different symbols than Liblouis
outputs by default, such as a ^ for dots 45, instead of a ~.
I'm basing my knowledge of the "proper BRF format" on what is output
by Duxbury when saving to the BRF format, and based on the format of
the files from the NLS WebBraille service.
