You have tested this? As I said, I had not. Taking another look I can see that it could match something like:
Code:
Code^_string^_12127

To stop this you would need to add something to the end of the pattern to match white space, but this would not match the end of the line. You could add a match for white space to the end of the pattern but then it won't match the end of the line. You could have two versions of my pattern: one with white space a the end and the other with the end of line anchor ($) at the end.

wsprintf

wsprintf(3C)						   Standard C Library Functions 					      wsprintf(3C)

NAME

       wsprintf - formatted output conversion

SYNOPSIS

       #include <stdio.h>
       #include <widec.h>

       int wsprintf(wchar_t *s, const char *format, /* arg */ ... ););

DESCRIPTION

       The wsprintf() function outputs a Process Code string ending with a Process Code (wchar_t) null character.  It is the user's responsibility
       to allocate enough space for this wchar_t string.

       This returns the number of Process Code characters (excluding the null terminator) that have been written.  The	conversion  specifications
       and behavior of wsprintf() are the same as the regular sprintf(3C) function except that the result is a Process Code string for wsprintf(),
       and on Extended Unix Code (EUC) character string for sprintf().

RETURN VALUES

       Upon successful completion, wsprintf() returns the number of characters printed. Otherwise, a negative value is returned.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
