[opensuse] Another slightly OT c question, howto handle extended ascii chars? >127

Listmates,

I'm parsing output that has the degree symbol in it in c. The character code
for the symbol is 167, but of course the ascii character set it limited to
0-127. Believe it or not, using a cut-n-paste into the strtok delimiter set
works, but that just feels like a cludge. Example:

const char delimiters[] = " +°,;:!-";
<snip 1st call to strtok>
token = strtok (NULL, delimiters);

Will break the string on ° correctly. But looking at how c is handling this
clude causes concern:

for (i=0;i<strlen(delimiters);i++) {
printf("%c %d\n", delimiters[i],delimiters[i]);
}

Yields:

32
+ 43
� -62
� -80
, 44
; 59
: 58
! 33
- 45

Hmm, any time I see the little � character, that's a bad sign. So, is there
any trick to handling the chars that are outside of the normal ascii chars,
but we seem to run into all the time? Is this the area of the thinly defined
wchar_t?
