We can check non-ASCII letters SGML/XML files by preparing "allowlist"
that contains lines which are allowed to have non-ascii characters,
although this list will need to be maintained when lines in it are modified.
I've attached a patch to add a simple Perl script to do this.

During testing this script, I found "stylesheet-man.xsl" also has non-ascii
characters. I don't know these characters are really necessary though, since
I don't understand this file well.
