For true-type fonts iText can use two approaches. One is to use an
encoding that will convert the Unicode character into a byte that will be
placed in the PDF content stream and is limited to 256 characters. The other
is to have the encoding IDENTITY_H that is actually a "no encoding"
encoding. This way each character will occupy 2 bytes in the content stream
but all the font characters are directly accessible.

No, thank you. I have enough information for Linux, Solaris and MAC
OSX. All the systems can use true-type fonts in the awt so a perfect match
is always possible.
