Styled Text Editor Component maximum size limit

Hi Appian Developers (and Community of course),

I hope that somebody from the Apprian Dev Team could answer / provide info.

I'm using the Styled Text Editor Component component (a!styledTextEditorField) to display content stored as HTML (display only, no edit required).

I'm wondering that is the exact maximum allowable value for the Size limit parameter? 

When I set 100K, it prompts "You reached the maximum character limit. Remove characters to continue." (it is an email conversation stored as html and it is expected to be large in size).

When I reduce it to 99K (set value for Size limit parameter to 99K), the error is gone.

Obviously, it lays somewhere between 99K and 100K but I would like to know what is the maximum allowed, to be able to display as much as possible of the text.

Or does it maybe depend on the encoding - single-byte/multi-byte?

However, the documentation states "... The parameter value is about equal to the number of characters allowed, including HTML formatting." - no mention of encoding.

In any case, I need info what is the maximum allowed, either in characters or bytes.

Thank You in advance for your time.

Regards,
