UI Text character limit


I am currently working on a private project and want a simple scroll view text in my menu screen to display my tutorial text (large amount of explenetory text). After being unable to display the text entirely I read in the forum that ui text is really limited (some indication in the editor would have been nice).

My question is whether there is a solution for the problem (haveing much text on screen)?

I dont understand what mean UI text is really limited.

There are no limits on texts.
