Hi,

I assume that you want to use LCDproc for writing to the display?

Then the above will most likely not work as the hd44780 driver maps
characters according to its configured charmap. Writing 0xDF to LCDd will
only work if you have a display with japanese character set and the charmap
is set to 'none' in the config.

Better is to write 0xB0 which is the degree character in ISO8859-1. It will
be mapped to the degree character on displays with the default and euro char
set.

Regards,
Markus
