How can I put a character limit on my field?

GDV2 introduces Validation for text fields. These fields allow you to enter an HTML5 regex rule to govern what is or isn’t allowed inside fields. Here are some example rules for limiting the character count. To use them, just copy from the portion in red and add to the HTML5 Regex field. More examples can be found here.

.{3,} 3 characters minimum
.{5,10} 5 to 10 characters
.{0}|.{5,10} Either 0 OR (5 to 10 chars)
.{0}|.{8,} Either 0 OR (8 chars minimum)
.{0}|.{0,40} Either 0 OR (40 chars maximum)

The rule for 40 characters maximujm is shown here being applied to the summary text field.
