It is a really bad idea, because it encourages non-portable documents, with the document creator not knowing why the other readers/users of the document aren't seeing what was written. > I think the best thing was if every character was included in every font, but > I realise that it probably isn't realistic. 102 012 code points are specifically defined as glyphs in Unicode 5.0; 137 468 code points are reserved for private use glyphs. There is an informal arrangement that specific glyphs are assigned to specific code points. Thus, a "complete" font will contain a minimum of 239 480 glyphs. Variants could easily double that number. ( All this is before one considers the book, italic, oblique, bold, black, etc. attributes, each of which is, when correctly done, a different glyph.) Creating even a "simple" set, that doesn't have the variants, much less different attributes, is a daunting task. Code 2000, arguably the most comprehensive font that is easily available, barely covers the entire Unicode 4.0 Plane 0, with 51 239 characters (61 864 glyphs). GNU Unifont contains 63 446 characters (63 446 glyphs) jonathon -- Ethical conduct is a vice. Corrupt conduct is a virtue.
