Andreas Lehmkühler commented on PDFBOX-3332:
--------------------------------------------
I've implemented a more general approach as discussed above.
- newly added mappings doesn't override existing mappings when using
Encoding#add (used for all Encodings but DictionaryEncodings)
- newly added mappings replace existing mappings when using Encoding#overwrite
(used for the Differences array in DictionaryEncodings)
This works for the given issue as well as for any other multiple character code
to name mapping.

> I'm using Apache PDFBox to fill a PDF Form. I'm using a TrueType font (not a
> default font) called 'Impact', pretty standard fare. In the template I have a
> field called "Title" that has the Impact font assigned. I use the code below
> to take that template and populate the field with a value that has several
> words in it.
> The issue is when you view the created PDF there are large spaces between the
> words. If you open the PDF in Acrobat and click on the field the text alters
> and the large spacing goes away. Editing the field in any way will
> permanently correct the issue, but I'm generating the forms to NOT be altered
> after the fact.
> I've tried the same experiment with the default fonts (Helvetica in this
> case) and the above issue doesn't exist. I can create a blank form and add a
> field and set the custom font and duplicate the issue.
> I've read that a similar issue was addressed in 2.0.0, PDFBOX-2062 but it was
> for changing font size, not a custom font.
