Oliver Schmidtmer commented on PDFBOX-5384:
-------------------------------------------
What about handling it here, in codeToGID:
{code:java}
--- a/pdfbox/src/main/java/org/apache/pdfbox/pdmodel/font/PDCIDFontType2.java
+++ b/pdfbox/src/main/java/org/apache/pdfbox/pdmodel/font/PDCIDFontType2.java
@@ -253,7 +253,7 @@ public class PDCIDFontType2 extends PDCIDFont
else
{
// fallback to the ToUnicode CMap, test with PDFBOX-1422 and
PDFBOX-2560
- String unicode = parent.toUnicode(code);
+ String unicode = parent.getCMap().hasUnicodeMappings() ?
parent.toUnicode(code) : null;
if (unicode == null)
{
if (!noMapping.contains(code))
{code}
The old implementation before the fix for PDFBOX-4322 returned "null" as there
was no unicode mapping, what then caused falling through to codeToCID at this
method.

> The attached PDF uses Tahoma fonts.
> It seems the correct font is used, but it uses the wrong glyphs.
> For example the "6" from the screenshot is definitely from Tahoma Glyph 25 /
> CID 54, where it should be "S" Glyph 54 / CID 83.
> The "=" in screenshot is Glyph 32 CID 61 where "Z" Glyph 61 CID 90 should be
> used.
