Hi Tilal,
Any luck with this issue? we have a client waiting on this fix and it’s been a good while now.

One thing I noticed, the superscript is a problem when it’s a superscript in the original word file. the instance when it is fine is when using the 2 and 3 characters in superscript shape (char 00B2 and 00B3)

Hi Akram,


Thanks for your patience.

We have further looked into earlier reported PDFNEWNET-38797 issue and as per our observations, it does not seem to be an issue with text extraction. Please note that PDF line ‘LTs 191 x10³/uL’ contains superscript as U+00B3 character and we have found no problems while extraction it. The next line ‘WBC 1 x 103/uL, RBC 1 x 103/uL, Hct 1%.t’ contains no superscript characters. It contains ‘3’ U+0033 characters. The superscript is emulated by little font size and upper shifting of ‘3’. It will be extracted as ‘3’ and it is normal work of text extraction. Text extraction has no special mode for handling font size and little vertical shifts.

Please take into account that text extraction has limited handling of text formatting. Whereas Abobe Acrobat extracts identical text from the document. In case you still require some special handling of superscripts while extracting text from such kind of documents, we may consider logging this requirement as an enhancement in our issue tracking system. Please acknowledge, so we may reply accordingly.
