I also checked https://answers.microsoft.com/en-us/windows/forum/all/which-characters-are-acceptable-for-a-computer/fddb4895-4295-47ab-a2b9-7773b329718c and pushed another patch to distinguish valid chars for server name and share name. The Cygwin test release containing this patch, 3.5.0-0.139.gcad3913ed8b1, is just being built.
