inside my web site structure there is a single plain text file that needs to be served as charset iso-8859-1. My web server is configured accordingly.
But I cannot process it in Middleman. If I put a text file with encoding iso-8859-1 in a folder within source (so that it gets copied to the same folder in build/), Middleman fails to do that because it encountered illegal UTF-8.
Can I configure that file (maybe with front matter), so that Middleman processes it in another charset?
