             Summary: [PATCH] Fix: "Foreign" characters are not rendered
                 Key: PDFBOX-1831
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1831
             Project: PDFBox
          Issue Type: Bug
          Components: FontBox
    Affects Versions: 2.0.0
            Reporter: John Hewson

This is a patch to fix PDFBOX-1691, I've opened it as its own issue because it's quite a large

The issue it fixes is that the Type 1 "seac" command was not implemented. Seac is a command
which draws a composite glyph from two other glyphs. This requires that the Type 1 renderer
has access to any of the other rendered glyphs in a CFFFont, which is why this patch is non-trivial.
The major change is that the CharStringRenderer has been refactored into a new Type1CharString
class and the CharStringConverter has been refactored into a new Type2CharString class. A
lot of code has been moved around, but overall this is a conservative patch, as most of the
code has not changed significantly.

As well as the patch, there are 3 new files:

+ fontbox/src/main/java/org/apache/fontbox/cff/Type1CharString.java
+ fontbox/src/main/java/org/apache/fontbox/cff/Type2CharString.java
+ fontbox/src/main/java/org/apache/fontbox/encoding/StandardEncoding.java

and two deleted files:

- fontbox/src/main/java/org/apache/fontbox/cff/CharStringRenderer.java
- fontbox/src/main/java/org/apache/fontbox/cff/CharStringConverter.java
