The matcher seems to be using the value produced by
`StringLiteral::outputString` which will "work" - until we support non unicode
encoding - but `StringLiteral::outputString` is really designed for debug, so
wchar etc are going to be escaped. I think this is going to be a difficult to
use interface.
We would be better off adding a way to convert back the string literal to
non-escaped UTF-8 ... except numeric escape sequence would not be preserved
(and might lead to replacement characters)
