Subject: Creating a multipage pdf with long text string

I am creating a pdf that among other components has very long strings that may produce text that are larger than a page. It is my understanding that if I add a text on a page, the text that will overflow will be clipped.

Is it possible to add a text on a page, so the library will split the text into pieces that fit onto multiple pages without clipping and add new pages as needed?

Thank you for your quick reply. Basically you recommend to treat a string as an html string and replace special characters (like TAB) to html. What about CR,LF?  Shall I replace them as well?

Does this technique use the kerning tables in the selected font, or just the left and right bearings of the glyph?

Really I do not know what you mean.
Maybe some other member will be able to answer to your question.
