Yes zdenko I've noticed the same problem where it shows the value of the
column 'script' is NULL, and when i try to change
the NULL value to real script name the unicharset file become unreadable
and thrwon error message when use it.

I wonder Is there a way to set the script name when creating unicharset
file? OR is there a way to edit the file without damage?
