That is a much larger issue, similar to our shipping our own timezone
database. What does it buy us?
o Do we ship it in our tarball?
o Is the license compatible?
o Does it remove utils/mb conversions?
o Does it allow us to index LIKE (next high char)?
o Does it allow us to support multiple encodings in
a single database easier?
o performance?

We assume the native toupper() can handle single-byte character
encodings. We use towupper() only for wide character sets.
