Please be aware that no one can tell you the better answer without the
details. this is a rough answer for the rough question. if you aren't
comfortable with it, please give us what you did, what happened and
what you were expected. otherwise there are no way to see what's wrong
in fontconfig.

The possible reason is, 1) there are no better fonts against the
query. which covers the code points in ug.orth. 2) the font pattern in
the query is wrong. 3) ug.orth has a bug.

You can put the following config to $HOME/.fonts.conf:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "/etc/fonts/fonts.dtd">
        <family>Your Font Family Name</family>
        <family>Your Font Family Name</family>
        <family>Your Font Family Name</family>

or if you want to use your font for Uyghur only:
    <test name="lang" compare="contains">
    <test name="family">
    <edit name="family" mode="prepend">
        <string>Your Font Family Name</string>

and similar for serif and monospace too.
