It shows properly in mupdf so must be some font change I've made.

@kjk
The legacy issue was more capitals than accents, however that issue was kept open on the transfer to MuPDF,
thus untested but first looks suggest older #442 (comment) may be related

the problem is that we pick up fonts:

0x000000dcbdcfd760 "Charis SIL Regular"
0x000000dcbdcfca70 "Charis SIL Bold"
0x000000dcbdcfcf00 "Nimbus Mono PS Regular"
0x00007ff79f64a530 "Symbol"

while mupdf picks up:

0x000000045896d268 "Charis SIL Regular"
0x000000045896c698 "Charis SIL Bold"
0x000000045896de38 "Noto Serif Regular"
0x000000045896cab8 "Nimbus Mono PS Regular"

We pick "symbol" instead of Noto Serif Regular" because it matches from windows installed fonts, which mupdf doesn't check.

The issue is that we don't ship with Noto fonts.
