It is a delimiter for a parser. I use this character because I am sure there wont be in the file. -- Thanks for your attention.

It is a delimiter for a parser. I use this character because I am sure there wont be in the file. I expect so - it's a pretty commonly used character in files that we have. (Since we deal with currency stuff.) Why, did you think it wouldn't? It's just another character, like é.

The compiler did not complain here but the if is not taken into acooount because for him there is no such a carachter. If I put a ^ instead, everything goes fine. while (--limit > 0 && (c = getc(fp)) != EOF) { if (c != '£' && flag != 0) { fputc(c, fpout); continue; } Back to top Alan Bellingham Guest Posted: Thu Nov 23, 2006 8:20 pm    Post subject: Re: £ character "Québec" <Once (AT) WasEno (DOT) ugh> wrote: Quote: not a function really.

Solution 1: use the -K compilation option - this tells bcc32 to use unsigned chars Solution 2: cast the '£' to be an unsigned char: if (c != static_cast<unsigned char>('£') && ...

No. It simply defines how C++ treats chars, i.e. as signed or unsigned (i.e. whether a top-bit is treated as 163 or as -93). It has nothing to do with the actual encoding. An encoding, like ISO-8859-1 defines which character gets which code. http://en.wikipedia.org/wiki/Iso-8859-1 http://en.wikipedia.org/wiki/ISO-8859-15 -- Rudy Velthuis [TeamB] http://rvelthuis.de/ "I think it would be a good idea." -- Mahatma Gandhi (1869-1948), when asked what he thought of Western civilization Back to top Rudy Velthuis [TeamB] Guest Posted: Sat Nov 25, 2006 8:48 pm    Post subject: Re: character At 15:43:14, 25.11.2006, Rudy Velthuis [TeamB] wrote: Quote: At 15:33:09, 25.11.2006, Qubec wrote: Solution 1: use the -K compilation option - this tells bcc32 to use unsigned chars Alan Bellingham Is this equivalent to coding:iso-8859-1 ?
