That was some time ago.. I was not sure back then how to handle that
with upstream data, so thanks for the bug report and the pointers.
I'll try to remember that.

+1 for the comment refresh in the test, keeping the test.

Perhaps this should use the codepoint rather than the non-ascii

Another thing would be to add some tests that cover the new characters
that get a conversion. Just a few of them in the new ranges, checking
the recursive case with is_letter_with_marks() would be fine.
