Alex Nevidomsky commented on PDFBOX-2649:
-----------------------------------------
I see. It's much trickier than I thought.
Did you mean
{code}
byte[] bytes = encode(codePoint);
{code}
instead of
{code}
byte[] bytes = encode(text);
{code}
in the code, though?

> {code}

> float wO = font.getStringWidth("O");
> float wP = font.getStringWidth("P");

> I can see that there is a confusion in the process between GID and CID
> values. The reason may not be entirely clear to me, but
> PDCIDFontType2Embedder.buildWidths(COSDictionary cidFont) seems to name "cid"
> something that in my opinion is still a glyph id. And when it comes to
> PDCIDFont.getWidth(int), the "widths" map that should presumably contain
> cid->width values in reality contains git->width.
