No contradiction here: the default glyphs in Apple's LastResort font show the English name of the script block TWICE (on the top and bottom borders of the surrounding thick frame).
That isn't true. That is only true in the case of one-word block names. Plenty of other block names are long, like ARABIC PRESENTATION FORMS-B.
Note that this does not require to include the true glyphs for characters of the localized name in the font, but a simplified version of them which is readable enough to be read, so even a bitmap version of the whole name could be used if the font is hinted to display that bitmap in the border only when the border thickness is large enough to display it. So there's no need to create very precise and beautiful letter forms for these indicators which should use a simple sans-serif stroke style to reduce the size of these last resort glyphs and of the whole LastResort font.
Please stop discussing font design, Philippe, if you wish to avoid offence. -- Michael Everson * * Everson Typography * * http://www.evertype.com
