If you are not flattening the field, then you can't manually set the kerning.
It's not part of the PDF spec for form fields.
What sort of system are you building that requires manual kerning (as opposed
to using the kerning tables in the font)?

Subject: Re: [iText-questions] PDFReader getPageContent() method returning
weird escape codes
The file is not flattened, so no problem there. But I am a little confused.
I need to manually allow the user to modify the kerning of the text inside the
field. I don't see in Ch 8 how FieldPosition would help. I guess I am looking
for a method that sets the kerning of the text that is used on the field.
I tried using getKernArray(text, bf) but I didnt see any set kern information.
Do I manully adust the array returned below?
PdfTextArray pdftxtarr= PdfContentByte.getKernArray(acr, bf);
Thanks

It depends: if you fill out the field without flattening, then an
appearance is created automatically. Kerning isn't used, not in the
appearance, not when the end user changes the text field manually.
If you want to flatten the field, then setField() won't result in kerned
characters. You can work around this, by getting the field positions (as
is done in chapter 8) and adding the content with the
showTextAlignedKerned() method.
> 2) How is tracking done?
Kerning is done automatically, based on the info found in the font.
Tracking isn't done automatically. If you position the text using the
methods of chapter 14 (text state), you'll have to do the math, and use
the methods that allow you to fine tune the word and character spacing.
Or you can use Text Arrays (arrays consisting of strings and numbers.
The numbers are measurements for the space between the strings). All
these methods are listed in chapter 14.
