Issue with Base64 extraction of Word docs?

[Dmitchell19]

Hello, do you know if there are any issues with Textpipe (Textpipe Pro 9.1) decoding base64 word documents? We are seeing issues with the document constantly being corrupted on decode.
As a test I created a simple filter that just does a Mime Encode (base 64) and then took the resulting generated file and ran it through another filter that had just a Mime Decode (base 64). The resulting doc created would not open in word saying the document was corrupted.
Do you have any idea why this would be the case?
thanks
