Thanks for your comments.

Mark for "Last":
I will use isNormalOrRangeFirst/isRangeLast instead of 0/1 to clarify
the intent.

Position of "Last" mark:
I put the mark 0/1 in the middle, i.e. before the category mark, so that
uniq command can ignore it with -f option which is used in your script.
If I put it after category mark, uniq command put a blank line before
"Last" entry, which will be replaced with undesirable "range" by sed.

Category "Co":
They are already removed in your original script, so I followed it.

I will submit a new patch to cygwin-patches@cygwin.com.

I will remake a patch based on UnicodeData.txt of version 10.0.

Thank you.
