John Hewson closed PDFBOX-1652.
-------------------------------
Resolution: Invalid
I'm struggling to see how a patch which modifies behaviour for these two
characters can be valid.
> TextPosition: Japanese alphabetic characters 30fc and 3005 treated as
> diacritics

> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 1.8.1
> Reporter: Christian Kohlschütter
> Labels: PatchAvailable
> Attachments: PDFBOX-1652.patch

>
> For the purpose of determining the position in text, the Japanese characters
> U+30fc (KATAKANA-HIRAGANA PROLONGED SOUND MARK) and U+3005 (IDEOGRAPHIC
> ITERATION MARK) are currently regarded "simple" diacritics. Apparently, they
> are fully-fledged characters in terms of text positioning.
> This can have the effect that when extracting text, some characters get
> actually reversed (particularly ーン can get ンー).
> A patch to fix this is attached.
