NOTE
Use of this pragma may cause a portability problem for some targets.
Be careful when initializing strings or multi-character constants that contain question marks.
Listing 30-2. Example of Pragma trigraphs
char c = '????'; /* ERROR: Trigraph sequence expands to '??^ */ char d = '\?\?\?\?'; /* OK */
By default, this pragma is disabled.
30.13 unsigned_char
Controls whether or not declarations of type char
are treated as unsigned char
.
Syntax
#pragma unsigned_char on | off | reset
Remarks
If you enable this pragma, the compiler treats a char
declaration as if it were an unsigned char
declaration.

NOTE
If you enable this pragma, your code might not be compatible with libraries that were compiled when the pragma was disabled. In particular, your code might not work with the ISO standard libraries included with CodeWarrior.
By default, this setting is disabled.
