In order spell checkers can apply,
M-x iso-tex2iso is nice for converting
TeX-encoded files to e.g.
UTF-8 encoded ones. But, in case a numerous files to convert, running this command in a batch mode would be helpful. How to do that?
Subsidiary question: (not for me, for a friend of mine owning a Mac) On OSX, how to make this batch thing a script with an associated icon that could "receive" (by "drag and drop") a file to be converted?
