-------------------------------------------------------------------
What do you mean "But I don't why excute"?
1) Anyway, I took a quick look and I think I understand what you mean.
PDFStreamEngine.java:380 is weird. From a string with "14" it makes a
non-existing unicode character 12596.
2) I also noticed: in PDType1CFont.java, in load(), the variable codeToNameMap
is filled but then never used. However mapping.getCode() (which would have
exactly the char values used in the PDF) is put there and not used. There
should be some logic that maps from mapping.getCode() to mapping.getSID() and I
suspect that it involves codeToNameMap. A perfect result would be that 49
somehow leads to 396, because 396 does exist in codetoGlyph and maps to the
correct glyph 0.
3) CFFGlyph2D has the same problem in the constructor as described in 2).
Adding codeToGlyph.put(mapping.getCode(), glyphId) would bring up a perfectly
rendered image, while the existing code brings only a lot of "?".
