Search fails after non-ASCII characters in scrollback (e.g. Korean or Japanese) #16
Description
I'm experiencing an issue where kitty-kitten-search fails to match search terms that appear after non-ASCII characters (such as Korean or Japanese) in the scrollback buffer.
For example, if the scrollback contains the following lines:
yt-dlp.sh
テスト.sh
skip.sh
Searching for "sh" will correctly highlight yt-dlp.sh and skip.sh, but not テスト.sh. It seems that once a line contains non-ASCII characters, any subsequent ASCII text on that line is ignored or skipped during marker creation.
