By default, all Unicode letters and numbers are allowed when you enable `unicode_usernames`. [Characters with a macron](https://simple.wikipedia.org/wiki/Macron) are allowed Unicode characters as well.

If you want to restrict the Unicode characters to characters with a macron, then I’d set the `allowed_unicode_username_characters` site setting to the following value:

```plaintext
[āǟǡǣḇc̄ḏēḕḗḡẖīḵḻḹm̄ṉn̄ōṓṑȫǭȭȱr̄ṟṝṯūǖṻȳẕ]

```

If you would like to allow only a subset of those characters, remove everything you don’t need from the list of characters.

Apostrophes aren’t a letter, so they aren’t allowed, and it’s not possible to add them to an allowlist. The reason is that allowing apostrophes in usernames could break functionality like mentions or quotes.
