A reader extension for SRFI 14 character set literals based on that of http://practical-scheme.net/gauche/man/gauche-refe_51.html#index-_0023_005bchar_002dset_002dspec_005d. Note that only a subset of that syntax is currently supported (individual characters and character ranges).
char-set-spec is a sequence of characters to be included in the character set. The following special sequences are supported:
- A range of characters from x to y, inclusive.
- The character -
- The character \
- The character ]
Any other backslash escape sequence is a syntax error.
