Q. Why can’t 3dIssue extract the Chinese language script from my PDF and why can’t I consequently search it?

A. The reason text is not extracted correctly is because the pdf most likely contains an embedded subset of a font.

For an explanation of this see http://www.glyphandcog.com/textext.html

The pdf is most likely created by acrobat pro and the font glyph names have been scrambled. This is why you can see the correct text in the pdf and in a rendered image or swf . Also, acrobat can decipher the glyph font subset encoding so you can copy and paste the text from acrobat. This is not the case with 3dIssue.
