How Can I Accurately Validate Persian Characters Using Regex?

Validation of Persian Characters using Regex

Issue:

When validating Persian characters using a regex pattern, the provided code ^[u0600-u06FF] $ may fail to include specific characters, such as گ, چ, پ, and ژ.

Answer:

To accurately validate Persian characters, consider using the following character sets:

Letters:

• ^[آابپتثجچحخدذرزژسشصضطظعغفقکگلمنوهی] $
• or the equivalent Unicode codepoints:

^[\u0622\u0627\u0628\u067E\u062A-\u062C\u0686\u062D-\u0632\u0698\u0633-\u063A\u0641\u0642\u06A9\u06AF\u0644-\u0648\u06CC]+$

Numbers:

• ^[۰۱۲۳۴۵۶۷۸۹] $
• or the equivalent Unicode codepoints:

^[\u06F0-\u06F9]+$

Vowels:

• [ ‬ٌ ‬ًّ ‬َ ‬ِ ‬ُ ‬ْ ‬]
• or the equivalent Unicode codepoints:

[\u202C\u064B\u064C\u064E-\u0652]

Combine these character sets as needed to match different aspects of Persian input. For example, for letters only:

^[آابپتثجچحخدذرزژسشصضطظعغفقکگلمنوهی]+$

Why Previous Patterns Failed:

While ^[u0600-u06FF] $ may seem comprehensive, it includes various characters not used in Persian, such as numerals and diacritics. Similarly, [آ-ی] covers additional characters that are not specific to Persian.
