[Bug 18724] New: RFE: font merging

Summary: RFE: font merging
           Product: fontconfig
           Version: 2.6
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: library
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Several major fonts like Arial and Droid Sans are created in two parts: a core
multifaced part and an Unicode extension (Arial Unicode, Droid Sans Fallback).
Splitting in two file sets allows people who do not need the extension part to
avoid installing it (since the extension is usually huge)

For historic reasons the two parts use different font family names, even though
from a functional user POW they are just two components of a single family.

There should be a documented way in fontconfig for font distributors to specify
via a config file "font foo is an extension of font bar, use it preferably when
bar is missing glyphs, do not show it as a separate item in font lists and only
allow access to the foo family when an application asks explicitely for it"

Make "documented way"  a "documented fonts.conf config pattern".

I think a target="scan" pattern should work here.

Nicolas, try something like this:

<match target="scan">
        <test name="family">
                <string>Arial Unicode</string>
        </test>
        <edit name="family">
                <string>Arial</string>
        </edit>
</match>

You then need to force fc-cache to recache.

Nicolas, did you try that?

I tried it in the droid font package and no one complained, so it didn't break
anything, but I didn't have the time to test it extensively.

I do wish CJK users spent some of their copious bugzilla time on it
