File to reproduce problem

If I try to add a word with diacritics to Index by choosing word -> Insert -> Table of Contents and Index -> Index Entry diacritic characters dissaper.
It works if I clear direct formatting after inserting diacritic character.
But this workaround not works in case I have diacritic character in font different from phrase.
As you can notice in content.xml diacritic character is still on it's place, but invisible.

Problem lies in https://opengrok.libreoffice.org/xref/core/sw/source/core/txtnode/fntcache.cxx?r=6de6231f#1293 where the copy of the string "wořd".copy(0, 3) returns "wor" instead of "woř".

Atm, I don't know if the implementation of the copy function of the OUString class is wrong or something in the fntcache.
Comment 7 Andreas Heinisch 2022-11-16 17:08:30 UTC
We should check if the u_CharType here:
if (nCopyStart + nCopyLen - 1 < rInf.GetText().getLength())
{
    switch (u_charType(rInf.GetText()[nCopyStart + nCopyLen]))
    {
        case U_NON_SPACING_MARK:
        case U_ENCLOSING_MARK:
        case U_COMBINING_SPACING_MARK:
            nCopyLen += 1;
            rInf.SetIdx(TextFrameIndex(nCopyStart + 1));
            rInf.SetLen(TextFrameIndex(nCopyLen));
            break;
    }
}

But somehow the kerning array should be adjusted, and there I miss to much information of how about it works.
