Kaz Wesley 0de490be24 Text literals: Accept unpaired-surrogate escape codes. (#9731) ... * Text literals: Accept unpaired-surrogate escape codes. Unpaired surrogates are not allowed by Unicode, but they occur in practice because many systems accept them; for example, they may be present in filenames on Windows (which are otherwise constrained to UTF-16). Programs written in Enso should be able to work with them, if only because they represent edge cases that should be tested when converting encodings and at other system boundaries. - Generalize the representation of interpreted-text-escapes in the lexer, so that we are not tied to the strict Unicode of Rust's `str`. - Move some doc-comment code from the parser to test utilities. - Simplify token serialization.		2024-04-18 09:21:05 -04:00
