In Odoo 17.0 (on-premise), I'm wondering if there's some way to limit the characters that can be entered into the text and multi-line text fields?

I'm finding that some customers are entering too much text in some fields, enough so that the text begins to overlap the next field, and the final document is difficult to read.  I've noticed that for multi-line text fields, this is accentuated if the person signing the field has the zoom setting in their browser much lower than 100%, because the size of the text does not scale in line with the zoom setting.

Limiting the characters that can be entered in a field is one way I've thought that might help reduce the chances of this happening.

Is there some way to customize the fields, either directly or with development of a customization module?
