Research direction
Examine how brittany currently handles Unicode symbols in source code by looking at the lexer and pretty printer modules. Identify where Unicode to ASCII conversion occurs and how the UnicodeSyntax extension is parsed. Consider adding a configuration option to preserve Unicode symbols or automatically detect the extension. Look at existing tests for similar features and create new test cases for UnicodeSyntax.
