Well, Tifinagh is not a cipher and writing Tifinagh with a Latin cipher is a bad idea. But things like bidi properties are only an issue if you are employing a cipher at the glyph level. I've already explained why I think ciphers, masquerading and transliteration should be carried out at the character level, not the glyph level. So if, you example, you wanted to write English in the Hebrew script, you should convert Latin characters to Hebrew characters, not Latin glyphs to Hebrew glyphs.
Agreed. But if you want to write English with the Theban script, as there are no Theban characters? Or what if you want to write English with the RTL version of the Theban script which I found mentioned at http://catb.org/~esr/unicode/theban/? That can't be done by glyph level substitution.
