== text profile should support anamorphic fonts ==
Proper Japanese support requires being able to distinguish characters whose glyph look similar, by stretching some characters along the horizontal axis. For example, the following are very similar:
- Katakana-Hiragana Prolonged Sound Mark U+30FC
- Horizontal Bar U+2015
On can use "1.5em 1.0em" to make the "Horizontal Bar" appear longer and different from the "Prolonged Sound Mark". This is usually done in LambdaCap, which actually supports stretching factors of 2.0, 1.5, 0.9 or 0.5.

If hard to implement, maybe some restrictions could be applied, such as applicable to spans with only one character, or else.
