This sounds to me like your word documents are using characters with character codes > 127 (0x7F) (extended 8-bit characters).
The \226 numbers are octal numbers, so \221 (0x91) for instance is not a quote (apostrophe), but a left single quote - but this is depending on the font you are using. So, it's left single quote in "Arial" or "Times New Roman", but it's just a bold pipe symbol in "System" font, where all characters from 0x7F to 0x90 and 0x93 to 0x9F are displayed as the same bold pipe.
So, the first thing to check is the font setting/mapping for your multiline EntryField.
If you store the data in the database and print them,
you of course have to print them using a program that supports the extended characters using an according font / character set.
