Font.font will, on Windows, use
IDWriteFontCollection::FindFamilyName(..)<br>
The docs for that appear to be silent on whether the matching
process will check all localized names,<br>
but it sounds like it must not. I don't see an alternative look up
API, such as one that accepts a locale arg.<br>
<br>
<a class="moz-txt-link-freetext" href="https://learn.microsoft.com/en-us/windows/win32/api/dwrite/nn-dwrite-idwritefontcollection">https://learn.microsoft.com/en-us/windows/win32/api/dwrite/nn-dwrite-idwritefontcollection</a>
<p>It seems like the app (which in this case means the FX
implementation) will have to do this itself which is going to be
tedious.</p>
<p>We would need to compare with every localized name of every font
on the system looking for a match.</p>
<p>And one annoying aspect of this is that until you've done that
exhaustive search you don't<br>
know if the name the application supplied is present at all on the
system.</p>
<p>How would you know that someone mis-spelled Arial as Ariel and
not that Ariel is the German localized name for Arial ?</p>
<p>So failed lookups will be slow.</p>
<p>In Java 2D we already do this but I'd have hoped DW used by FX
was better than this than GDI used by 2D.</p>
Also note that<br>
(1) fixing this for DW wouldn't help Linux or Mac so there'd need to
be separate implementations if they also don't do it automatically<br>
(2) There isn't any FX API which lets you enumerate or access
localized names, so as you note, that also is an issue.<br>
Although I'm actually a little surprised FX finds 幼圆 but reports
YouYuan. I would have thought it would be consistent.<br>
<br>
I'm also a little surprised that it has taken this long for anyone
to even implicitly ask for FX to support localized font names.<br>
Java2D has had this support for a very long time.<br>

<div>Hi,</div>
<div><br>
</div>
<div>We recently noticed a problem: For fonts with localized
names, <font face="monospace">Font.font(String)</font>
can only find the font based on the localized name in the
current locale.</div>
<div><br>
</div>
<div>For example, the Chinese version of Windows comes with
a font called "YouYuan", and its Chinese name is "幼圆".</div>
<div>When the system language is Chinese, JavaFX has the
following behaviors:</div>
<div><br>
</div>
</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div dir="ltr">
<div><font face="monospace">jshell>
Font.font("YouYuan")<br>
$2 ==> Font[name=System Regular, family=System,
style=Regular, size=13.333333015441895]<br>
<br>
jshell> Font.font("幼圆")<br>
$3 ==> Font[name=YouYuan, family=YouYuan,
style=Regular, size=13.333333015441895]<br>
<br>
jshell> $3.getFamily()<br>
$4 ==> "YouYuan"</font></div>
</div>
</blockquote>
<br>
<div>As you can see, we cannot find the font based on the
English name, we can only use the Chinese name.</div>
<div>But <font face="monospace">Font::getName()</font>
returns the English name, so we can't get the Chinese name
from the <font face="monospace">Font</font>.</div>
<div>This makes it impossible to generate a style sheet based
on a <font face="monospace">Font</font><font face="arial, sans-serif"> object, </font>because </div>
</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div dir="ltr">
<div><font face="monospace">"-fx-font-family:
\"%s\";".formatted(font.getFamily())</font></div>
</div>
</blockquote>
<div dir="ltr">
<div>will not work with these fonts.</div>
<div><br>
</div>
<div>The only workaround I can think of is to generate a
mapping table from English names to Chinese names like this:</div>
</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div dir="ltr">
<div><font face="monospace"><br>
</font></div>
<div><font face="monospace">Font.getFamilies().stream().collect(Collectors.toMap(it
-> Font.font(it).getFamily(), Function.identity()))</font></div>
</div>
</blockquote>
<div dir="ltr">
<div><br>
</div>
<div>But this seems like a lot of overhead :( </div>
<div><br>
</div>
<div>So, I want JavaFX to provide the following features:</div>
<div>
<ol>
<li>Regardless of the current system language, <font face="monospace">Font.font(String)</font> should be
able to find the font by its English name;</li>
<li>Provide a new method <font face="monospace">Font::getLocalizedFamily()</font>
to get the localized name of the font.</li>
</ol>
</div>
