Subject: 26.3; (gnus-display-mime) does not handle “post” accents
Date: Sun, 30 Aug 2020 16:58:48 +0200

[Message part 1 (text/plain, inline)]

When running (gnus-display-mime) on the attached message, it displays “J’ai rate´...” instead of “J’ai raté...”.  When decoding the base64 part by hand with “base64-decode-region”, save it to file with raw-text encoding, and reverting that file, the accented chars display correctly.

This has nothing to do with gnus.  Characters from different fonts
cannot be composed.  It just means that your default font does not have
a glyph for the COMBINING ACUTE ACCENT.

Ah, thanks, that makes sense.  It is not my default font (which supports the composition) but the one picked up by HTML rendering.  How can I substitute/influence the fonts chosen by mm-shr?  (This problem seldom happens, I do not want to disable the use of proportional fonts for HTML emails.)

Best,
C.

shr/eww uses the 'variable-pitch' face for displaying proportional
text. Just M-x customize-face it.
