<p>I'm not a font wizard, the only a consistent thing about this
issue is that the glyph indices are always off by 2. The linked
otf bug tracker issue has that same issue, and that is using a
completely different font.<br>
<br>
If I had to debug this, I would probably think of something where
some rare condition is true for the affected systems where some
part of the code does a +1 on the glyph index to adjust for
something but should instead do a -1. And since that condition
seems to be very rare, normal testing doesn't catch that.<br>

There's some hard-coding of names to files in WindowsFontMap.java<br>
Maybe that's part of it, but its very much a guess.<br>
It would be interesting to try a build which excludes using that
pure "optimization"<br>

Very odd. Possibilities :<br>
- font mixup : the glyph ID is for a different font.<br>
- cmap bug : the incorrect glyph ID is used for the
codepoint.<br>
- the font is a unicode variable font something goes wrong
as a result - I doubt this one as the IDs should be the
same.<br>
- something else :-)<br>
<br>
Is the D3D pipeline being used ? <br>
What's the user locale as shown by windows ?<br>
<br>
To get some idea of what fonts are being used they could run
with -Dprism.debugfonts=true <br>

<p>I'm not able to reproduce it, but some of my users
are. If anyone who knows the font renderer maybe wants
additional information or has some ideas on what the
users can try to either fix or diagnose the root
cause, I can relay that request to them.</p>
<p>I can ask them to try other JavaFX applications, but
either way how that goes, it doesn't show the cause.<br>

<b>Subject: </b>Windows default
font glyphs are rendered wrong
on some systems</span><o:p></o:p></p>
</div>
<p class="MsoNormal"><span
style="font-size:12.0pt">Hello,</span><o:p></o:p></p>
<p>for some of our users, the font
glyphs of the default Windows font
are wrong by an offset of +2. E.g.
the letter D is rendered as F, the
symbol - is rendered as /, and so on
... However, the glyph spacings and
kernings are using the correct
values for the original letter, only
the actual glyph itself is wrong.
This is happening on the latest
24-ea build on Windows 11, but also
occurred on version 21 a while ago.
I wasn't able to reproduce it
myself, only some users were.<o:p></o:p></p>
<p class="MsoNormal"><span
style="font-size:12.0pt">This has
happened now for multiple users of
our application, so I figured to
report it (Didn't find this in the
bug tracker). </span><o:p></o:p></p>
<p>Here is there issue, next to how it
should look like:<o:p></o:p></p>
<p class="MsoNormal"><span

<p>(It is in danish because the user
played around with the language
settings to troubleshoot)<o:p></o:p></p>
<p>There was no explicit -fx-font set,
so the application uses the default
one. When the users change to using
-fx-font: Roboto, which is bundled
with our application, the glyphs are
rendered normally. So this issue is
specific to certain fonts.<o:p></o:p></p>
<p>If there's any additional
information required, I can relay
that request to our affected users.<o:p></o:p></p>
