printf and unsigned char
-
Hi all How can I print unsigned char's to the console? I compile with the "default unsigned char" option as this has to run on Linux, but in Windows it just spits out garbled characters. Thanks :) I rated this article 2 by mistake. It deserves more. I wanted to get to the second page... - vjedlicka 3:33 25 Nov '02

unsigned char c = 'A';
printf("%c",c);

Thanks Nish, but I'm not sure that will help :confused: I'm reading Afrikaans text from a file. And Afrikaans has all those nice o's, e's, with various thingies on them. Here's some code:
FILE *input;
char inputfile[50] = "input.txt";
char word[50];
char yesno;if ((input = fopen(inputfile, "r")))
{
while (!feof(input))
{
fscanf(input, "%s", word);if (!trieIsMember(word)) { //here the "upper" (128+) chars dont print properly to console //the char are shown properly in the debugger though, no prob in linux printf("Spell Error: %-20s Add word? ", word); yesno = getchar();getchar(); //for enter if (tolower(yesno) == 'y') trieAdd(word); }}
fclose(input);
}Any ideas? I rated this article 2 by mistake. It deserves more. I wanted to get to the second page... - vjedlicka 3:33 25 Nov '02

OK I found out what the problem is. It appears to be an ANSI/ASCII conflict. The letters appear fine in ANSI charset, but comes out funny in ASCII what it appears they are using for the console. Now the question is: How can I print ANSI strings properly to ASCII? And I thought DOS was dead.... ;P I rated this article 2 by mistake. It deserves more.

leppie wrote: I'm reading Afrikaans text from a file That makes a huge difference. Now you basically need wide character versions of all the functions you have been using :-) Replace printf with wprintf, fopen with _wfopen, fscanf with fwscanf etc... Regards, Nish

I can assure you those are NOT wide. :) These are the ones: ëêéô , but the command prompt just does not spit them out correctly. I get what looks like an epsilon, omega, theta and integral characters, in that order. [edit]δΩΘ⌠ , these are the ones I get on the console[/edit] Perhaps its to do with regional settings...? I will have a look. :) There is an options for codepage for non unicode programs. It was set to English US. I have change this now, but requires a reboot. I have not planned a reboot yet, but perhaps Monday will be a good day. Windows XP has been running 2wks 4days 8hrs 33mins. :eek: I rated this article 2 by mistake. It deserves more.

One possible way to display
unsigned charinprintfis to convert it to anintand display theintas achar.int x = 240; printf("%c .. %d\n", x, x);This will surely be slow for large strings! :~ Hope this helps you someway!:-O Rgds, Nirav:-) * The world stands aside to let anyone pass who knows where he is going! - David Jordan * -
