This question may be best answered by Thomas, but I thought I’d post it generally and see what else might come of it.
Why is support for Luxembourgish listed with Adobe Latin 5 but not any of the smaller sets? According to the spreadsheet that Thomas provided with his blog post
about the Adobe Extended Latin sets, it seems that this support hinges on the unencoded mcircumflex
characters. But I haven’t been able to find any documentation on the role or necessity of these characters in this language, not in any of the usual places.
Can anyone shed some more light on this?
