What is the character priority order when sorting manuals by name?

The character priority order is as follows:

1. Space
2. Symbols (!#$%&'()*+,-./)
3. Numbers (0-9)
4. Symbols (:;<=>?@)
5. Uppercase Letters (A-Z)
6. Symbols ([\]^_`)
7. Lowercase Letters (a-z)
8. Symbols ({|}~)
9. Other characters

Checkpoints when the order is not as expected

• Check if there are spaces at the beginning of titles
• Check if different characters with the same appearance but different character codes are being used
  Example: Hyphen (-) U+002D and Minus (−) U+2212
