By default, terminus-font will install a lot of pcf font in different encoding. However, I only need the one with unicode, which is the superset of other fonts. By introducing pcf fonts file with these unnecessary encoding, it causes problems with qt. See bug report: https://bugreports.qt-project.org/browse/QTBUG-22599#comment-253138 The attachment is a ebuild with minimal uses flag. Reproducible: Always

yes, you can say technically say "unicode is a superset of all other encodings" if you mean "every character that can be represented in other encodings can also be represented in unicode". but it does not mean that they are codepoint compatible (data represented in one encoding does not directly convert to utf8). only ascii & iso-8859-1 are compatible in that regard, and only when speaking of utf8 encoding. there are still people who choose to use those encodings, so you can't really classify them as "unnecessary". adding a flag (like USE=minimal) that only installs utf8 encodings seems reasonable to me as it's the long term convergence point.
Should USE=minimal be enabled by default?
(In reply to Davide Pesavento from comment #4) i kind of want it to be, but maybe it should have a better name than the USE=minimal dumping ground ? USE=pcf-unicode-only maybe ? don't want to make it sound like the flag applies to psf files (since, iiuc, it's not possible to load a full unicode based font into the Linux console as it only supports up to 512 codepoints simultaneously). the proposed patch could be simplified a bit by using wildcards: # Only the ter-x* fonts are unicode (ISO-10646-1) based rm -f "${ED}"/usr/share/fonts/terminus/ter-[0-9a-wy-z]* || die
Ping... Is this patch really to go?
