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 <x80> in more [less]
and vi. Nutshell, the file was fubar'd.
