I'm trying to print a character at coordinates (x,y). The following code
gives me a segmentation fault because I'm trying to pass a single character
instead of a pointer to a string:
print_char(x1, y1, pr_char)
float x1, y1;
char pr_char;
{
XDrawString(display, displaywin, gc, (int)x1, (int)y1,
pr_char, 1);
}
Could someone please tell me how I should go about printing the single
character "pr_char"?
Thanks,

I would like to know if there is a way to print the foreign characters(above 127) to an xterm without writing a full blown X application. I would like to print French words with the correct accents on the letters. The font "fixed" has these character, but I can't get xterm to print them. E.g. putchar(233); doesn't print an 'e' with an accent grave like I would like it to. Please mail suggestions to me! Tom Epperly epperly@cs.cmu.edu or epperly@osnome.che.wisc.edu

Unfortunately, the R3 xterm from MIT has some bugs that prevent it from being
8-bit clean. Also, you have to make sure that you've done the appropriate
stty command to set the terminal to pass 8-bit characters. Fixing xterm
is relatively straightforward (several people posted suggestions about it
several months ago): you change the definition of Char to be unsigned and
rip out the silly loop in input.c that strips the eighth bit.
The R4 xterm will support both input and output of 8-bit characters (yup,
really "meta" characters in your non-X editors).kit@EXPO.LCS.MIT.EDU (Chris D. Peterson) (09/29/89)

The R4 Athena AsciiText widget will also support 8-bit characters. (Yea I know that makes the name slightly incorrect) Chris D.
