Title: Explicit use signed char for included font data to enable cross-compile

I'm trying to cross compile sfml for an arm based board, which failed due to a different
default behavior for char.

From ISO/IEC 9899:1999, 6.2.5.15 (p. 49):
The implementation shall define char to have the same range,
representation, and behavior as either signed char or unsigned char.
