Description

When filling AcroForm fields the text supplied to setValue might contain control characters such as \n \r, \t and others which leads to an {{ java.lang.IllegalArgumentException}} for most fonts as there is no glyph to represent these.

We could enhance the processing of the string provided to provide proper replacements similar to how Adobe Acrobat handles that.
