I think I didn't change the matching condition
in kpathsea for Windows. I don't know a reason of the above
behavior. Probably a feature of the program updmap.

However, I will change the matching condition in the next TL 2019:
case-sensitive matching is done even on Windows for trees with ls-R.

Best,
