Which Config File Controls Font Selection on KT 5.3.2

[xiaoguixp]

After upgrading my KT's firmware to 5.3.2, I can see only one font available (黑体) when reading Chinese files. While for English files, three fonts are available (Caecilia, Helvetica and Caecilia Condensed). I want to know which configuration file controls this? How can I add another Chinese font and let the system display it for selection?

I don't want to use the USE_ALT_FONTS method, because all the stock fonts will show up.

In firmware 5.1.2, I could add a config file in /etc/fonts/conf.d directory to intercept the rendering of the three families for English files, like the following example to display custom Chinese font for the Caecilia Regular family:

   	
<!-- Search for CJK_Serif.ttf and CJK_Serif_Bold.ttf and add them to CJK_Serif_Family -->
<match target="scan">
    <test name="file" compare="eq">
        <string>/mnt/us/fonts/CJK_Serif.ttf</string>
    </test>
    <edit name="family" mode="assign">
        <string>CJK_Serif_Family</string>
    </edit>
    <edit name="style" mode="assign">
        <string>Regular</string>
    </edit>
    <edit name="weight" mode="assign">
        <const>medium</const>
    </edit>
</match>
<!-- scanning Bold font -->
<match target="scan">
    <test name="file" compare="eq">
        <string>/mnt/us/fonts/CJK_Serif_Bold.ttf</string>
    </test>
    <edit name="family" mode="assign">
        <string>CJK_Serif_Family</string>
    </edit>
    <edit name="style" mode="assign">
        <string>Bold</string>
    </edit>
    <edit name="weight" mode="assign">
        <const>bold</const>
    </edit>
</match>


<!-- Intercept the Caecilia Regular family and append the CJK_Serif_Family -->
<match target="pattern">
	<test name="family">
		<string>Caecilia Regular</string>
	</test>
	<edit name="family" mode="append">
		<string>CJK_Serif_Family</string>
	</edit>
	<edit name="family" mode="append">
		<string>Kindle Symbol</string>
	</edit>
</match>

Now the above method no longer works because there is only one font available for selection for Chinese files.

Is there a config file that we can modify to add more font to be displayed?

No, I believe, dialog fonts' enumeration is handled entirely in Java code. I think, you should either use JBPatch to modify Java code so that it would not skip necessary fonts, or use USE_ALT_FONTS and trick to hide unnecessary fonts at Fontconfig level.
