Locale aware sorting crashes on macOS 15 with OSError

### Describe the issue

I start weblate from source code and it throws an OSError. It may be related to that the character set does not support non-Latin characters. I have written scripts to reproduce this.

### I already tried

- [x] I've read and searched [the documentation](https://docs.weblate.org/).
- [x] I've searched for similar filed issues in this repository.

### Steps to reproduce the behavior

1. I started weblate from the source code as described in the documentation
2. Error occurs

### Expected behavior

not to crash

WARNINGS:
?: (security.W004) You have not set a value for the SECURE_HSTS_SECONDS setting. If your entire site is served only over SSL, you may want to consider setting a value and enabling HTTP Strict Transport Security. Be sure to read the documentation first; enabling HSTS carelessly can cause serious, irreversible problems.
?: (security.W008) Your SECURE_SSL_REDIRECT setting is not set to True. Unless your site should be available over both SSL and non-SSL connections, you may want to either set this setting True or configure a load balancer or reverse-proxy server to redirect all connections to HTTPS.
?: (security.W012) SESSION_COOKIE_SECURE is not set to True. Using a secure-only session cookie makes it more difficult for network traffic sniffers to hijack user sessions.
?: (security.W018) You should not have DEBUG set to True in deployment.
?: (weblate.W033.Subversion) Failure in loading VCS module for Subversion: git: 'svn' is not a git command. See 'git --help'.

### Additional context

Here is a test script to reproduce the problem

```python
import locale

def main():
    try:
        locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
        print("Using locale:", locale.getlocale())
    except locale.Error:
        locale.setlocale(locale.LC_ALL, '')
        print("Using default locale:", locale.getlocale())

    choices = [
        ('en', 'English'), 
        ('zh', '中文'),  
        ('ru', 'Русский'), 
        ('ar', 'العربية'), 
        ('fr', 'Français')
    ]
    
    def key(tup):
        return tup[1]
    
    try:
        res = sorted(choices, key=lambda tup: locale.strxfrm(key(tup)))
        for item in res:
            print(f"  {item[0]}: {item[1]}")
    except Exception as e:
        print(f"sorted fail!: {type(e).__name__}: {e}")
        
        for i, tup in enumerate(choices):
            try:
                transformed = locale.strxfrm(key(tup))
                print(f"item {i} ({key(tup)}): success")
            except Exception as e:
                print(f"item {i} ({key(tup)}): fail - {type(e).__name__}: {e}")

if __name__ == "__main__":
    main()
```

The above code runs on my Mac (15.3.1) with the following results:
Using locale: ('en_US', 'UTF-8')
sorted fail!: OSError: [Errno 22] Invalid argument
item 0 (English): success
item 1 (中文): fail - OSError: [Errno 22] Invalid argument
item 2 (Русский): fail - OSError: [Errno 22] Invalid argument
item 3 (العربية): fail - OSError: [Errno 22] Invalid argument
item 4 (Français): success
