Regular Expression to limit characters to 5000

I need a regular expression to simply limit the number of characters 开发者_如何学JAVAin a textarea to 5000. If there are more secure regular expressions I could use, I am open to suggestions.

Thanks

^.{0,5000}$ should work. Although using a regular expression for this is probably an odd choice.

You will always get the job done with:

^[\s\S]{0,5000}$

• First there´s a character class that says: match whitespace (\s) or non-whitespace (\S) -- i.e any possible character
• Repeat that between zero and 5000 times.
