What is the max number of characters that a text field can be defined to hold?

I am using Ninox stand alone - no need to sync to the cloud for my purposes. I have a d=table that includes a text field, but have found I cannot add as much as I had hoped to - is there a maximum number o characters a text fir=eld can be defined to contain? In the parameters under "Edit fields" I entered 10,000 as a maximum - there was no error message or indication that would be a problem - but after copy and pasting multiple paragraphs into that field, even though everything did seem to be recorded, after quitting and restarting Ninox it cut off the text field at some point, after about 6900 characters (including spaces)
