[Alpine-info] How to attach, send and then see .csv files

[Iosif Fettich]

Hello, dear alpineers,

I wonder if someone has a receipt about how to best manage .csv files when 
sending them as attachments.

I have an reports.csv file for which I can see the following directly:

$ file report.csv
report.csv: Little-endian UTF-16 Unicode character data

If I attach the file, it gets attached with mime-type

Application/OCTET-STREAM

When then reading the file, as there is no mailcap entry for .csv files, I 
end up not being able to see the file correctly.

If I add a

text/csv   csv

mime type to .mime.types, the file is sent as a TEXT/csv attachment, but 
when I try to view it, (because there is no mention about the non-ASCII 
UTF-16 characterset in the header ?), I see it garbled with lots of " @" 
sequences.

I'm in doubt now about what the best way to manage should be, both for 
sending as for receiving, in order not only to be able to see myself the 
files that I am sending, but also making it in a way that is compliant 
with what others would need or expect about a .csv attachment.

Probably adding _both_ a .mime.types entry like above and a mailcap entry 
for TEXT/csv I'm "solved", but I'd like to know if there's a way to solve 
this issue in a somewhat more general way.

Thanks for any suggestions.
