Regex for character in a multi line text field?

[LawesD]

On the off chance that anyone has already solved this issue:

We want to limit the text to 800 characters in a multi-line text field. We can only seem to get it to work using regex on single lines. 

TIA

Hey @LawesD

^[\s\S]{0,800}$

should work across multiple lines.

All signs point to yes. Thanks Met!
