[issue2541] Unicode escape sequences not parsed in raw strings.

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

I mean: now that raw strings cannot represent all unicode points (or
more precisely, they need the file encoding to do so), is there a use
case for "raw-unicode-escape" that cannot be filled by the
unicode-escape codec?

Note that pickle does not use "raw-unicode-escape" as is: it replaces
backslashes by \u005c. This has the nice effect that pickled strings can
also be decoded by "unicode-escape".

That's why I propose to completely remove raw-unicode-escape, and use
unicode-escape instead.
