[xep-support] Inexplicable problem with font family

[Jim Melton]

Dear RenderX,

I have used XEP for a couple of decades to produce an ISO/IEC 
international standard; your organization was kind enough to provide me 
and a small handful of my fellow editors (in ISO/IEC JTC 1/SC 32) a 
license to use XEP all these years.

Very recently, two of us (me and Jörn Bartels, copied on this message) 
have acquired and configured new laptop computers. Both of us 
encountered a very strange problem that caused an error message to be 
issued whenever we attempt to transform a .fo file into .pdf if the 
document uses Arial Unicode MS.

The error that we get is:

    could not find any font family matching "ArialUnicodeMS"; replaced
    by Helvetica

Both of our xep.xml files contain a font-group thus:

<font-group xml:base="file:/C:/Windows/Fonts/"label="Windows 
TrueType"embed="true"subset="true">

In that font-group, we both have the following:

<font-family name="ArialUnicodeMS">
<font><font-data ttf="ARIALUNI.ttf"/></font>
</font-family>

Both of us definitely have this font, using that exact font name 
(including capitalization), instlled in ...\windows\fonts\ The installed 
font shows in that directory as "Arial Unicode MS Regular".

On my new laptop, I eventually created a new font-group:

<font-group xml:base="file:/D:/RenderX/fonts/ttf/"label="Windows 
TrueType"embed="true"subset="true">

and moved the font-family lines (shown above) into that new font-group; 
I also coped the font file ARIALUNI.ttf into the directory 
D:\RenderX\fonts\ttf\.  This "cured" the problem on my laptop, although 
I absolutely cannot figure out why.

Unfortunately, my colleague Jörn Bartels did exactly the same thing on 
his new laptop, and he continues to have the problem of getting that 
error message.

Can you help us figure out WHY this happens only on our new Windows 10 
laptops and HOW we can fix the problem on Jörn's computer?

Many thanks,
    Jim
