Character count and limit enforcement

The Rich Text Editor automatically counts the number of characters in the content while typing, using the ShowCharCount property. The characters count displayed at the bottom of the editor. You can limit the number of characters in your content using the MaxLength property. By default, the editor sets the characters limit value to infinity.

The character count indicator changes color based on usage thresholds:
