lex for Chinese character
Hi,
I need to read one chinese char using lex. I tried using "." ( period ) for pattern matching but in vain.
Could anyone suggest me how do i proceeed.
Sample pgm: to read a chinese char in single quotes.
%{
#include <locale.h>
%}
%%
\'.\' printf("SUCCESS\n");
. printf("Failed\n");
}
%%
main()
{
setlocale(LC_ALL,"");
yylex();
}
This always prints me "Failed" message. I cannot use '.+' for matching for my application.
I can view the chinese char with locale settings on my machine. I am using linux machine . Locale set is : zh_CN.utf8.
Thank You

Hi everyone!
This is my very first post, sorry if I'm not posting in the right category.
I'm trying to match a newline "/n" using lex/yacc.
For example,
print(9,'\n',8)
should print
9
8
now do I write a regular expression to match exactly " '\n' "
Thanks! (1 Reply)
