Subject: 24.5; fail to display svg file containing accented characters
Date: Wed, 1 Apr 2020 12:45:00 +0200

When editing an SVG drawing, hitting ctrl-C+ctrl-C toggles display mode
between source text and graphical. This works fine as long as the source
does not contain accented characters. When the source contains accented
characters, the graphical display is the same as for an erroneous SVG
file, except right after the file has been read or written. In the
example below, it is enough to replace the 'é' of "Bézier" by an 'e' to
not see this effect:

I can reproduce this in Emacs 24.5 and in 26.3, but not in the latest
pretest of Emacs 27.  So I think this problem was already solved.
Would it be possible for you to try the Emacs 27 pretest? it's
available from alpha.gnu.org.

Thanks.

More information was requested, but none was given within 3 weeks, so
I'm closing this bug.
