Nico Prenzel updated PDFBOX-3881:
---------------------------------
Description:
PDDocumentInformation e.g. getAuthor() honors the byte order of the extracted
string and removes the byte order mark signs.
But if the extracted string does only contain the byte order mark signs the
corresponding string "þÿ" is returned.
Is this the intended solution?
I'd appreciate to remove the byte order mark signs also, if the extracted
string does only contain these signs.
Problematic code:
{code:java}
public String getString()
{
if (this.bytes.length > 2)
{
if (((this.bytes[0] & 0xFF) == 254) && ((this.bytes[1] & 0xFF) == 255))
{
return new String(this.bytes, 2, this.bytes.length - 2,
Charsets.UTF_16BE);
}
if (((this.bytes[0] & 0xFF) == 255) && ((this.bytes[1] & 0xFF) == 254))
{
return new String(this.bytes, 2, this.bytes.length - 2,
Charsets.UTF_16LE);
}
}
return PDFDocEncoding.toString(this.bytes);
}
{code}
