---------------------------------------
Summary: Slow string to hex conversion in ToUnicodeWriter
Key: PDFBOX-3418
URL: https://issues.apache.org/jira/browse/PDFBOX-3418
Project: PDFBox
Issue Type: Improvement
Components: PDModel
Affects Versions: 2.0.2
Environment: Ubuntu 14.04 LTS
Reporter: Michael Doswald
Priority: Trivial
The ToUnicodeWriter.writeTo(OutputStream) method converts a lot of shorts and
strings to hexadecimal strings. This is done with String.format and therefore
not very efficient.
The ToUnicodeWriter.toHex(int) and ToUnitcodeWriter.stringToHex(String) methods
could be rewritten to generate a char-array and being generally more efficient.
