Feature Request: Syntax - Allow escape of any special character

Syntax request: Allow special characters to be escaped that don't actually need it?

Some users do not search for special characters very often, and don't remember which require the escape character and which don't. Yes they can look it up when their regex fails. It would be a nice usability enhancement if the engine would syntactically ignore an escape character with a symbol that doesn't need it.

Thanks for consideration of the idea.

The issue names no files, tests, or entry points. Start by locating Boost.Regex's syntax parser and existing escape-handling tests, then confirm the supported behavior and compatibility expectations before proposing a change. Done means unnecessary escapes are accepted without changing required escape semantics, with regression coverage.
