This patch is to fix the compiler warning error: C4245. The issue will happen
if the below build option is enabled:
*_*_*_CC_FLAGS = -J.
That's because the value of ('A' - 'a') is a negative value, which will
be converted to an unsigned type if CHAR8 is treated as unsigned:
Src -= ('A' - 'a');
The above issue is also recorded at:
