For lower-case characters with combining top diacritics, the diacritics are automagically substituted with case equivalents in the ccmp feature in the lookup ccmp_Other_2.
I don’t want that to happen, so how do I deal with this? Is there a way to automagically turn it off so that only lower-case diacritics are used with the lower-case glyphs?
That can’t be disabled. I would need to add a switch for it.
Please do so. I really can’t use the case versions for lower-case in this case.
I added a “Use case marks for double marks” custom parameter. It will not be in the list, but copy paste the string in the search field and hit “Add”.
I’ve run into the next issue: Eg. when I add the combining tilde after an upper-case glyph that doesn’t have a precomposed character, the combining tilde is used, but I want my upper-case variant to be used in those cases. How do I solve this?
Can you give an example combination?
Yup. In the image you see LATIN CAPITAL LETTER SMALL CAPITAL I and LATIN CAPITAL LETTER OMEGA. With the previous Use case marks for double marks both majuscule forms of these two characters are using the minuscule diacritic. You can compare with Ĩ and Ũ which are both pre-composed and therefore are using the correct case-form alternative glyph.
