PdfFormFillerUTF-8

pdfformfiller 1.0-alpha is a command line utility for filling in Adobe PDF Forms.

For WWW: A php example, that uses fast Unix pipes (and no disk write permissions required on the host), is provided.

It support UTF-8 (Russian, etc.).

Proper escaping functions are provided in the php example.

Well known pdftk utility can be used for filling in PDF Forms.
However, I was not able to get the version pdftk1.4 to work with UTF-8.
It's XFDF format support UTF-8 encoding, and assumes Adobe uses an UTF-8 font by default. Whereas, Adobe Readers (at least upto version X) do not, and UTF-8 text is entered by pdftk but is not shown in its form until user clicks on the form and edits it.

In PdfFormFiller, you can use the -font option to specify a UTF-8 font to use to fill in the forms to resolve this issue.

Also, our fields input file format is much simpler then XFDF of pdftk that requires XML parsing.
