You can figure out what the original request is from the logs before evaluating
test/edit patterns like:
FcConfigSubstitute Pattern has 4 elts (size 16)
        family: "Arno Pro"(s)
        style: "Regular"(s)
        lang: "ja"(w)
        prgname: "fc-match"(s)

"(s)" means the strong binding which is explictly added into the pattern
against the request except "prgname". "(w)" is the weak binding. it could be
also added through API but usually that may means *here* it was added by
fontconfig for the certain reason.
Anyway, please make sure it doesn't appear after "FcConfigSubstitute
donePattern has..." line. otherwise that isn't the one what you are looking
for.

As long as they deal with it properly, no. otherwise yes. anyway, I meant how
applications shows the information from fontconfig depends on their code. they
just did so intentionally. it isn't fontconfig fault.
