OK, so I'll take this as mostly unrelated to the patch.

It's somewhat more clear what you're talking about, but I'm still not
sure what specific pieces of code you would want to omit from libc.so.
Which of the following would you want to remove or keep?

- UTF-8 encoding and decoding
- Character properties
- Case mappings
- Internal message translation (nl_langinfo strings, errors, etc.)
- Message translation API (gettext)
- Charset conversion (iconv)
- Non-ASCII characters in regex and fnmatch patterns/brackers
