Find forbidden characters

This script finds characters that should not occur in the raw text, because it might confuse the conversion scripts or it is plainly improbable that a character appears in a book of a certain period (an IPA character cannot be expected in a 17th century book). The characters are collected in the "configuration" file.
For further replacements, just add them to file with the following syntax:

<string to be replaced> = <replacement string>
