Attached is a diff with a change to dhelp_parse.rb which sets
Encoding.default_external explicitly, so that even if LANG=C, it uses UTF-8
instead of US-ASCII as the default for opening files. By my (limited)
understanding of Encoding.default_external, this should have the same
effect on opening files as replacing LANG=C with LANG=xx_XX.UTF-8 would.
On my machine, without the patch, I see the same errors with LANG=C as the
others here. With the patch, I do not.
Hope to help,
