Comment 9 for bug 670758

At the moment in the Ubuntu Font Family 0.69 release we are already shipping with a number of incomplete/partial Unicode blocks, where the current glyphset covered is only a subset of the Unicode listing for the full block:

  Alphabetic Presentation Forms
  Currency Symbols
  Cyrillic
  General Punctuation
  Greek and Coptic
  Superscripts and Subscripts

I'm inclined to believe that we don't want to set a hard rule either way (purely blocks, or purely scripts), but, just like in the case of the music notes for DVD subtitles (bug #655350) we work out on a case-by-case basis what is a /sensible/ set, depending on what the interactions are.

We want full, coherent contributions, rather than odds-and-sods, but at the same time, needing to cover 256 glyphs when instead 50 could be prioritised is something I don't think we want to turn down.

As Ben notes, the selling point if ticking off coverage of use-cases (scripts, or geographic regions), and these (except for the complex scripts) don't tend to match up one-for-one.
