The problem with character "?" (pdf->epub)

Konstantin · 09-16-2015, 04:22 PM

I would be grateful for assistance of advabced User!

I try to convert some text from pdf-file to epub-file by means of Calibre. And I want to remove all page headers in epub-file after the conversion.
The problem is that the built-in Master of replacement doesn't want to find any regular expression, containing character "?", in pdf-text. So I can not remove symbol "?" from all page headers, containing it.
The Master of replacement easily removes the text of any page header, but the character "?" - if it is - always is left in epub-document after the conversion.
Why?
How can I kill off this character in output epub-text?

Thanks in advance!

Have you tried escaping it?

Let me thank You, Mr. eschwartz!
I have tried escaping with the help of the backslash and now all is OK!!!

The symbol "?", that I hate now, disappeared in a flash!

You're welcome.

Be sure to check out the complete Regular Expressions guide on that site -- I found it to be very informative and easy to follow, it taught me almost everything I know about regular expressions.
