We have a configure check for that, but I don't know how to replicate
that on Windows.

If ucol_strcollUTF8 is not available, we have code to convert to UTF-16.This is the same code that is used for
non-Windows.

There is a test specifically for ICU, which you can run with

make check EXTRA_TESTS=collate.icu.utf8
