This was a fairly simple change thanks to previous work on making the Ident type abstract and the fact that PGF.CId already uses UTF-8-encoded ByteStrings. One potential pitfall is that Data.ByteString.UTF8 uses the same type for ByteStrings as Data.ByteString. I renamed ident2bs to ident2utf8 and bsCId to utf8CId, to make it clearer that they work with UTF-8-encoded ByteStrings. Since both the compiler input and identifiers are now UTF-8-encoded ByteStrings, the lexer now creates identifiers without copying any characters. **END OF DESCRIPTION*** Place the long patch description above the ***END OF DESCRIPTION*** marker.

DESCRIPTION
The Grammatical Framework (=GF) is a grammar formalism based on type theory.
It consists of
* a special-purpose programming language
* a compiler of the language
* a generic grammar processor
The compiler reads GF grammars from user-provided files, and the
generic grammar processor performs various tasks with the grammars:
* generation
* parsing
* translation
* type checking
* computation
* paraphrasing
* random generation
* syntax editing
GF particularly addresses four aspects of grammars:
* multilinguality (parallel grammars for different languages)
* semantics (semantic conditions of well-formedness, semantic
properties of expressions)
* grammar engineering (modularity, abstractions, libraries)
* embeddability in programs written in other languages (C,C++,
Haskell, Java, JavaScript)
