Research direction

The issue names no source file or test; start by reproducing the TypeScript example in the TS and JS Grammar Extension and locating the grammar rule that classifies character classes. Done means the escaped hyphen follows the expected behavior, with a regression check if the repository's existing tests cover this grammar.
