I habitually write e.g. organise instead of organize, but I'm aware that I am sometimes
writing for publication in a US magazine or book, and that the orthographic conventions
differ. So I rely on language tagging and spellchecking and, to a lesser extent, grammar
checking to 'convert' my particular brand of UK English to US English.
Now let's say that I have a text in typical modern German, which I decide I want to
display in blackletter type (noting your accurate objection to use of the specific term
fraktur). What degree of this conversion should I be able to rely on to be automated, and
what degree will require editorial intervention *in the text*? I don't know the answer to
that question, and I suspect it is something that could generate a good deal of debate.

There's a pretty big assumption in OpenType, or at least in implementations of OpenType
Layout support, that script tags are mappable either to Unicode ranges or to discreet
subsets of Unicode characters drawn from different ranges. A user may be able to set
language in an application (e.g. InDesign CS2 ME) to access specific glyph variants or
shaping behaviour, but the script is usually (always?) presumed from the characters in the
I'm not commenting on whether this is a good idea, but so long as it is the case U+0041 is
always going to be <latn> script.
