Please provide a justification for this requirement to support EBCDIC and
UTF-16, included systems that would be impacted today by this change.

I spoke with Ulrich Drepper directly, and he did point out that the design idea
behind using <Uxxxx> sequences was indeed to support the locales on systems
that had other encodings like EBCDIC, but with the rise of UTF-8 as the defacto
standard, no such systems have really materialized.

I disagree strongly with this, why use '<a>' instead of 'a'? Please provide
strong rationale for why we should keep using the <Uxxxx> format.
