=={{header|ALGOL 68}}==
The definition of Algol 68 is character set independent. Not only variables may be represented in Unicode, all other language elements may be so represented. All that is required is that the representation language must be capable of being translated unambigously back and forth into the reference language.

One can have Unicode in identifier or subroutine names and also in package or class names. Use of Unicode for the last two purposes is, due to file and directory names, dependent on the filesystem.
