To aid in the discussion of how to specify the normative behavior for
the 'text-combine-horizontal' property, I put together a page of
examples showing the appearance of tatechuyoku using width-specific
variant glyphs and synthetic glyphs created by simply scaling the
underlying full-width or default digit glyphs.
http://people.mozilla.org/~jdaggett/tests/tategaki-examples.html
Each date or address shows five renderings, using the codepoints and
settings described below:
1. full-width digits, half-width variant enabled for 2 digits, third-width variant enabled for 3 digits
2. full-width digits, scaled to half for 2 digits, scaled to third for 3 digits
3. default digits, no features or scaling
4. default digits, half-width variant enabled for 2 digits, third-width variant enabled for 3 digits
5. default digits, scaled to half for 2 digits, scaled to third for 3 digits
