Capital letter accent

The picture of that looks like an accent on capital letters in the operating system Ubuntu 21.10.

Text document example

There is a table inside the text document.

The left side of the table contains fonts that do not correctly display accent on capital letters.

The right side of the table shows the fonts in which the accent on capital letters is correctly displayed.

Are you sure that’s the correct Unicode encoding? You seem to be using a combining character, and any misalignment is simply caused by individual fonts lacking anchors for positioning (which would make this issue “NOTOURBUG”). Still, we can improve the situation a bit by upgrading our copy of HarfBuzz.

No reply, so assuming this is notourbug.

Comment 5 ⁨خالد حسني⁩ 2022-12-20 18:21:38 UTC

The Unicode code points are correct, the text is using combining acute accent (U+0301) which should work. Opening the ODT content.xml, one sees things like:

<text:p text:style-name="P10">T<text:span text:style-name="T1">́</text:span>est.

So the base letter (T) and the accent are in separate spans, which is tracked in bug 61444. But I winder where these spans are coming from, seems similar to bug 113134 (though I’m sure I saw a more general bug open about this but can’t find it).
