I used
int ch, not char ch;
Also, just found some throwaway code that [of course] never gets
pitched, and
found the for chars >= 128, it's a wide character.
while (( ch = getwc(stdin)) != WEOF)
{
if (ch == L'\xe2')
{
if ((ch1 = getwc(stdin)) == L'\x80')
{
printf("'");
/* check for and swallow last of the
trio */
if ((ch2 = getwc(stdin)) == L'\x90')
{
continue;
}
}
}
else
{
putchar (ch);
}
}
I wrote the above to get rid of openoffice TXT that was still cluttered
with the
trio of wide characters that output one apostrophe.
Last night I used pdftotext to translate a pdf file; it was cluttered
with a slew of
^L's, which == '\014', and wound up with a greater slew of in
more [less]
and vi. Nutshell, the file was fubar'd.

Hello,
First of, this isn't really a BSD question.
Second, if you have an example code we might be able to help.
Presumably, you want to read a capital C with cedille? (0x80 128 Ç)
Example from: http://www.cplusplus.com/reference/clibrary/cstdio/getchar/
compiled on FreeBSD 7.2 with gcc 4.2.1 output:
"
Enter text. Include a dot ('.') in a sentence to exit:
sfeo
sfeo
Çsdfa
Çsdfa
"
besides.. 0x80!=0200
it's 0200 octal which is 128 decimal...
Might be why it doesn't work for you.
Greetz,
Mark

anybody know why getchar() doesn't see 0x80 == 0200? if getchar() is limited to 7-bit characters, what then? % od -c file shows me that every character fits into 8 bits, so getwchar() is the next thing. but doesn't getwchar grab wide-chars only: 16 bits? tia, guys, gary -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix http://jottings.thought.org http://transfinite.thought.org The 5.67a release of Jottings: http://jottings.thought.org/index.php ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
