First, I was giving Braille as an example of the kinds of things people should look for. So I'm not pushing this particular issue; I agree that based on Braille usage that we don't really need it in IDNs. However, a discussion of why significant edge cases are excluded is something that belongs in Rationale, in case the question comes up.<br>
<br>Secondly, however, Cary's rationale is not a useful test. While a Braille cell can have different representations in other characters, so can a great many letters. An "a" represents something quite different in English than in, say, French. There are many Han characters that represent something quite different in Chinese than in Japanese. The letters "chat", mean something quite different to a Frenchman than to a Welshman. Similarly a particular braille sequence doesn't mean the same to a blind Frenchman as to a blind Welshman.<br>

</div>In that case, you've answered the question, because if you need to<br>
know what language it's in even to know what character a given cell<br>
means, then that cell is not a character written "as a letter" but<br>
instead as a pointer to a letter, provided you have the right context.<br>
