signed char problems

Having big headaches with the signed char problem.
I need to read in various text file, which are in several different languages. These text strings thus include extended ascii characters - those above 127.

As EVC++ only sees signed chars ( even with the _CHAR_UNSIGNED compiler pragma set) it gives you incorrect output values i.e

'ä'=0xe4=byte(228)=signed char(-28)
'ü'=0xfc=byte(252)=signed char(-4)
'ö'=0xf6=byte(246)=signed char(-10)

I need to obtain the correct ascii values for these letters :evil:

'ä' should give the decimal value 132.

any help would be much appreciated ( even a dirty fix would do).

Jim.

'ä' should give the decimal value 132.

char a = 'ä';
// has a decimal value of -28

unsigned char b = (unsigned char) a;
//has a decimal value of 228

how do I get the correct ansii 132 decimal value?

Jim.

ps. Am I doing somefink real dumb?

That makes no sense. You compiled the exact code sample you posted? How are you obtaining b's value, via the debugger?

This page probably answers the "why ANSI" part... but I don't know the conversion routine (maybe you'll have to go through ANSI->UNICODE->ASCII?) ... or just stick to Unicode in the first place if you can.
