Tilman Hausherr commented on PDFBOX-1956:
-----------------------------------------
The visual is just a bunch of glyph *images* that happen to make sense to you
because you can read.
To make a check if the pdf is searchable one solution could be to test whether
the extracted words can be found in a dictionary of common words.
