HELP: How to add custom chars?

[biohazardxxx]

Hi,
custom chars like the degree symbol ° do not display correctly. (Sam for €ÖÄÜöäü)
Any hint how to add them to the cp437font.h?

(Great library thanks!)
Best regards

Every line of the font file represent an 8x8 matrix for that character.
Every number, the hexadecimal representation of a line
Eg binary 00001111 = 0x0F = first four leds off, last four leds on.

Find out if ° is really not in the font (see that there are a lot of characters without a a proper "printable" comment) and change the address corresponding to ° to a series of hex values that draws a °
