Tilman Hausherr commented on PDFBOX-5155:
-----------------------------------------
Here's what I think happens:
{code}
// first try to use a ToUnicode CMap
String unicode = super.toUnicode(code);
if (unicode != null)
{
return unicode;
}
// if the font is a "simple font" and uses
MacRoman/MacExpert/WinAnsi[Encoding]
// or has Differences with names from only Adobe Standard and/or
Symbol, then:
//
// a) Map the character codes to names
// b) Look up the name in the Adobe Glyph List to obtain the Unicode
value String name = null;
if (encoding != null)
{
name = encoding.getName(code);
unicode = unicodeGlyphList.toUnicode(name);
if (unicode != null)
{
return unicode;
}
}
{code}
Because of the workaround for /ToUnicode streams in
{{PDFont.loadUnicodeCmap()}}, {{super.toUnicode()}} is successful, so the later
code is never used. It's possible that one earlier PDFBox version can extract
this file here properly, but these would fail with others.
