TextPosition returns some characters with wrong case
Hi,
When I try to use TextPosition to get text in a PDF file, it sometimes gives
me related character with changed case.
For example, The text in the pdf is like this:
"BEBEK RANGE ROVER "
And PDFBox returns the text like this:
"bebek RANGe ROVeR "
I'm using processTextPosition() method to get text. What could be the
problem, I can't figured out how to solve the problem.
Thanks.

no you can not use height font, if the font embended is not matching
standard unicode font (check that with a font editor) then you can try to
produce a matrix to go from the "special" font unicode mapping to the
standard one.
that's just an idea, I am just a user...

Used font in the PDF file is "Kingfisher-Heavy", is it one of the unmatching
fonts?
Can I use character height values in order to solve correct this problem?
For example; if I can get the height for each character in the pdf file, I
can compare this value with nearer characters, then I could convert a
lowercase character to uppercase using some logic. Does PDFBox provide an
interface to get height values for textposition objects, or characters?

Hello,
May be a font problem, the embended one in the pdf file is matching the
standard font mapping to unicode?
