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
singledatabase easier?o performance?

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