Instead of capturing the output of each echo and uniset invocation, wrap
the whole section in a group command and redirect its output all at
once.

The value is the same on both uniset invocations, so "Don't Repeat
Yourself" applies.
Since we're in a subshell already, there's no need to unset UNICODE_DIR
at the end.

"uniset/uniset" is a relative path; there's no need to prefix it with "./".

By using a here document instead of the echo/uniset sequence, the final
structure of the generated file becomes obvious.

The value is the same on both uniset invocations, so "Don't Repeat
Yourself" applies.
Since we're in a subshell already, there's no need to unset UNICODE_DIR

Strictly speaking, you are not introducing your own subshell to
prevent the environment from leaking (i.e. you used "{...}" not
"(...)" in the previous step). The reason you can do this is
because the generation of UNICODEWIDTH_H file is the last thing in
the subshell.
I'll reword it to "Since this is done as the last command, ..."

I don't introduce a new one, but we're still in the outer subshell that
starts on line 12 "( cd unicode &&".
