Validate Unicode Length With Regex

Question

How can I validate ۱۳۹۱/۰۹/۰۹ string with Regex I want the length of each separate slash be exact as {4}/{2}/{2} the Unicode range is [\u06F0-\u06F9]. I have problem with length checking.

Accepted Answer

You can use the following regular expression:

```
"^[\u06F0-\u06F9]{4}/[\u06F0-\u06F9]{2}/[\u06F0-\u06F9]{2}$"
```

You're probably missing the `^` to make it start the match at the beginning of the string and the `$` to make it end the match at the end of the string. Without these changes strings that were longer, but that contained your expression would yield as a match.

With this change a match is only successful if the string contains your pattern and does not have any extra characters to the left or to the right of the target pattern.
