Facing issue with Style Text Editor Field when setting the character limit to 4000

I am using “Style Text Editor “ Field for one of the input field and set the character limit to 4000 .It is showing validation for 99 percent itself that It has reached the maximum limit.

May I know Why it is happening like this and how the bolded/Italic values consumes the field characters and showing the warning without reaching 100 percent.

How this issue can be resolved?

The Styled Text Editor’s sizeLimit counts bytes of stored HTML (including <b>, <i>, <p>, etc.), so formatting and multi‑byte characters consume part of the 4000‑byte limit and trigger the max limit warning before you reach 4000 visible characters.

As Shubham already mentioned - all styled text carries unseen HTML formatting (and that includes even when you don’t add styling but put in paragraphs).  For increased visibility into how it roughly calculates this, show the saved raw text in something like a paragraph field component (or view it in the variable’s held value in the interface designer), where you can see the plain HTML characters it inserts as the user adds text to the field.
