IMO, define an alias for chinse-two-byte to keep compatibility would be better.

You're right ,I think.

Emacs's compatibility advantage is a significant benefit of the ecosystem. Therefore, keeping compatibility is a more reasonable solution when dealing with outdated code

Emacs 24.3, released in 2013, has already been around for 10 years, and given the modern features introduced after Emacs 28, it's reasonable to expect correct spellings.

But rx--categories is a constant variable, create an alias is hard.

I don't know how to hack rx, rx--translate-form, rx--translate-category for use the modified rx--categories to provide chinse-two-byte.

May be directly drop typo is better.

I mean keep compatibility for pangu-spacing, not the GNU Emacs. As I know, most of user used this package did not use the latest Emacs.

I don't have machine installed Emacs 24.3.

I have checked Emacs 28.2/29.4 in Nixpkgs, it seems work and no side effects.

Emacs versions 21.1 to 24.3 have incorrect spellings, later versions ( above 24.3 ) may include both correct and incorrect spellings (not sure).

Latest versions keep the correct spellings and remove the incorrect ones.

It doesn't seem like a good idea to hardcode the version number, but I couldn't find a way to detect the current available rx--categories, maybe it's just something I've missed?
