Manipulate file with non-printable characters

[Frustated]

Hi, all.

I am in need to download a file from an MVS mainframe via FTP, open it,
replace a few text characters, and put it back on the mainframe.

The issue is, the file contains non-ASCII characters.

The method I tried was to use CFFTP binary download option and convert it to
Base64 on my ColdFusion server (6.1MX).
I then converted the strings I want to search and replace on the file to
Base64, and did a find and replace on the converted file.

Needless to say, it did not work (could not find the strings to replace). Do I
need to put the base64 converted file into an array, and then do the search and
replace on all rows? If so, how?

Thank you for any suggestions.

Mauricio
