Hi FlashCode,

Thanks for quick reply.

I think your idea is better than mine. I also checked result with some
test-cases, it seems to work fine.

Thanks for the patch, it is committed.

I changed some things:
- use of only one function to not duplicate code, with new argument: "int use_screen_size", to use size on screen instead of number of chars,
- use of "use_screen_size" == 0 only in text emphasis (I'm not sure it was intentional in your patch to not use width any more in many calls to the function).

My tests were OK, but if you think something is wrong with these changes, please let me know.

When highlighting a word in string containing full-width chars ahead
of the search word, wrong position is highlighted.

This is a patch for this bug.

This bug is caused by position counting error in
"gui_chat_string_real_pos" function.  According to the source of
"gui_color_emphasize" function, argument "pos" for function
"gui_chat_string_real_pos" is expected to be a number of UTF-8 chars,
but inside "gui_chat_string_real_pos" function, argument "pos" is
treated as the width of string on screen. So, if argument "string"
doesn't contain full-width chars, it's always fine. But if there is
full-width char ahead of search word, wrong position is highlighted.
