Previewer not displaying special characters in text-based files

[jggautier]

Just reporting that are not being displayed in files text files, like CSV files and .txt files, like this one at https://doi.org/10.7910/DVN/YZRJWD/A0SND4:

@djbrooke tried to see if this might be a known issue with one of the previewer's dependencies but didn't find anything, I think.

Looks like the code retrieves the file as binary and doesn't set the encoding (UTF-8?). It looks like the underlying library used can retrieve the file directly from the URL and may handle that. If not, it may be something we need to set in the call. @anncie-pcss - are you able to look at fixing this somehow?
