HTML pattern Arabic letters

Question

I want to insert the Arabic letters in the pattern just like the English letters

pattern="[a-zA-Z0-9-_. ]{1,30}"

I have no idea how to accomplish the action.

Answer 1

The range for Arabic and Persian are shared so this code could be used for Arabic too.

[أ-يa-zA-Z]

This is the reference for finding the character range of Unicode languages:

preg_replace and preg_match arabic characters
