[chirp_devel] [PATCH 0 of 2 ] Fix charset in ft8x7 drivers

I under estimated the problem of "icon" chars supported by this yaesu radio when I wrote drivers. To avoid crashes under OSX I now have restricted the CHARSET to printable (and supported by radio) chars that are ASCII. Unsupported chars are now replaced with a * when found in labels. I don't really love this solution but I didn't find a better way to manage those chars.

If ther are ways to support full charset or at least some more then new CHARSET please let me know (eg. here https://bg8net.dyndns.org/OpLog/yaesu_charset.png the full 857 table).
