Description

The PDPageContentStream.drawString take a String as argument, it construct a COSString of the input.
If the input contain chars above 255, the COSString is prefixed 0xFe, 0xff and the bytes are taken from the
input as "UTF-16BE" encoded.

Back in the drawString method this unicode16 encoded COSString is appended as a "ISO-8859-1"

appendRawCommands( new String( buffer.toByteArray(), "ISO-8859-1"));

The result of this is that a line with UTF-16 chars is shown prefix with þÿ, and with double space between the other chars.
The chars above 255 are shown as the two corresponding ISO-8859-1 characters.

As a side question to this observation, is there an alternative way to use Pdfbox, to support UTF16?
