class Symbols extends AnyRef
To encode non-ASCII characters ("symbols") in strings, Isabelle uses a proprietary encoding which
encodes a symbol as a substring \<name> where name is the name of the substring. (Thus, strings
containing symbols are ASCII strings.)
There is a loose correspondence between symbols and Unicode codepositions that
is documented in a machine readable format in etc/symbols in the Isabelle distribution.
This class translates between Isabelle's encoding and Unicode strings.
If the default values for this class's constructor are appropriate, consider using the static functions Symbols.symbolsToUnicode and Symbols.unicodeToSymbols instead of instantiating this class.
