I have found that a few files are not txt, but binary ones. I can open them with file:read-binary. However, the reference to XML can be confusing because I am not dealing with XML.

Hi,

I am trying to open a bunch of files with file:read-text, but I get the error [file:io-error] invalid XML character: #0, even I am not dealing with XML. Any idea why this happens? Thanks!

Perhaps as XQuery strings impose XML rules for allowed characters? Can you read out the files as binary hex or base64?
