From my understanding, the \d in JavaScript should match non-english digits like ۱۲۳۴۵۶۷۸۹۰, but it appears to not be functioning correctly.
You can check out this jsFiddle for more details: http://jsfiddle.net/xZpam/
Is this normal behavior or is something off?
It appears that JavaScript lacks support for this feature, among other limitations in the language regarding RegExp. However, there exists a library known as XRegExp which includes a unicode addon. This addon allows for unicode support using the \p{} category definition. For instance, by utilizing \p{Nd} instead of \d, you can match digits:
<script src="xregexp-all.js" type="text/javascript"></script>
<script type="text/javascript">
var englishDigits = '123123';
var nonEnglishDigits = '۱۲۳۱۲۳';
var digitsPattern = XRegExp('\\p{Nd}+');
if (digitsPattern.test(nonEnglishDigits)) {
alert('Non-english using xregexp');
}
if (digitsPattern.test(englishDigits)) {
alert('English using xregexp');
}
</script>
Replaced \p{N} with \p{Nd} as it seems that \d is similar to \p{Nd} in non-ECMA Script Regex engines. Credit goes to Shervin for bringing this to light. Check out this fiddle by Shervin as well.
Did you know that JavaScript does not have native support for Unicode regex matching? This limitation is actually quite common across many programming languages.
If you want to learn more about using Unicode in regular expressions, check out this helpful resource:
If you visit the documentation for Google Chrome (https://developer.chrome.com/docs/js/reference/global_objects/regexp), you will learn that:
\d
Identifies a numeric character in the standard Latin alphabet, also represented as [0-9].
The character \d is the same as using [0-9], as explained on MDN website.
According to the MDN documentation, you can use the RegEx Test to match a digit character in the basic Latin alphabet.
This is equivalent to matching characters within the range [0-9].
Identifies a numeric character. Essentially the same as [0-9].
For instance, using /\d/ or /[0-9]/ successfully identifies '6' in the phrase "Room 6 is where you'll find your keys."

Absolutely, it is perfectly normal and accurate that \d specifically matches the Ascii digits 0 through 9. The definitive source for this information can be found in the ECMAScript standard. While not the simplest of reads, clause 15.10.2.12 (CharacterClassEscape) explicitly states that \d represents "the ten-character set encompassing the numbers 0 to 9".
Absolutely, the use of \d does not match properly with non-English numbers in JavaScript. However, similar to other peculiar aspects of JavaScript, you can still verify non-English numbers (such as Persian numbers) in JavaScript by utilizing something similar to the code provided below:
/[۰, ۹]/.test("۱۲۳۴۵۶۷۸۹۰"); //true
