[NTG-context] Hair space and non-breaking hyphen

Hi, I've seen two interesting Unicode characters that I would like to use: Hair space: U+200A (it's supposed to be a space that's small, used around emdashes sometimes). Non-breaking hyphen: U+2011 (an hyphen where the word is not supposed to be broken by hyphenation). I would like to know if I can use them in Context. Is Context going to respect non-breaking hyphens in hyphenation algorithms? Is hair space going to be what it is supposed to, no matter which font I use? Thanks, Maurício
