bug#47235: 28.0.50; Suboptimal display of decomposed character sequences


From: Philipp Stephani
Subject: bug#47235: 28.0.50; Suboptimal display of decomposed character sequences
Date: Thu, 18 Mar 2021 15:35:40 +0100

On some systems (e.g. my current GNU/Linux system), "A" followed by
U+0308 COMBINING DIAERESIS isn't displayed as a single glyph.  See the
attached screenshot, which compares this character sequence with the
canonically-equivalent precomposed form "Ä".  The precomposed glyph
form looks better, and it would be great if Emacs could use it for the
composite variant as well.  Also see
