[ruby-core:120448] [Ruby master Bug#20994] C API - How to Create Classes with Non-ASCII characters in Name

Issue #20994 has been reported by cfis (Charlie Savage).

----------------------------------------
Bug #20994: C API - How to Create Classes with Non-ASCII characters in Name
https://bugs.ruby-lang.org/issues/20994

* Author: cfis (Charlie Savage)
* Status: Open
* ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [x64-mswin64_140]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
As part of Rice (Ruby C++ bindings), I am experimenting with using unicode characters to make more readable class names (see https://ruby-rice.github.io/4.x/stl/stl.html#automatically-generated-ruby-classes).

I am experimenting with class names like this:

```
Map≺string≺char≻٬vector≺complex≺double≻≻≻`
``` 

Where < and > are actually Unicode characters precede (\u227A) and succeed (\u227B).

In Ruby this works fine:

``` ruby
irb(main):01> class Map≺string≺char≻٬vector≺complex≺double≻≻≻
irb(main):02> end
=> nil
irb(main):013> Map≺string≺char≻٬vector≺complex≺double≻≻≻.new
=> #<Map≺string≺char≻٬vector≺complex≺double≻≻≻:0x0000021114674c98>
```

However, this fails using the Ruby C API `define_method`. Passing a `char*` that is utf8 encoded fails because `define_method` calls `rb_intern` which calls `rb_intern2` which forces the use of ascii encoding (see https://github.com/ruby/ruby/blob/5fec9308320e8b377681ef19b0cd46d53f94e8ac/symbol.c#L818).

I thought I might be able to define the class using ascii characters, and then call `rb_define_const` to add in a utf8 encoded name, but that also has the same problem.

My question - how does one create class names that have non ascii characters in them via the C API?

Issue #20994 has been updated by cfis (Charlie Savage).


Sorry, above where I wrote `define_method` I of course meant `rb_define_class`.

Ah - I found `rb_define_class_id_under` which works.

Issue #20994 has been updated by nobu (Nobuyoshi Nakada).

Tracker changed from Bug to Misc
Status changed from Open to Closed
ruby -v deleted (ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [x64-mswin64_140])
Backport deleted (3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN)

Or you can assign an anonymous class to that constant.
