There are escape sequences defined for six Unicode characters (&, <, >, LRM, RLM, and NBSP), but not a general purpose escape mechanism for characters. It's generally recommended that character escapes be provided so that difficult to enter or edit sequences can be introduced using a plain text editor. E.g. something like HTML's &#x123AB; syntax.

Escape sequences are particularly useful for invisible or ambiguous Unicode characters, including zero-width spaces, soft-hyphens, various bidi controls, mongolian vowel separators, etc.

For advice on use of escapes in markup, but that is mostly generalisable to other formats, see http://www.w3.org/International/questions/qa-escapes
