\usepackage[utf8]{inputenc}
get's me "Package inputenc Error: Keyboard character used is undefined
". I don't get this error on my MacBook.Conversely,
\usepackage[latin1]{inputenc}
causes the same error on my MacBook, but not on my iMac.Both machines use the same MacTeX / TeXLive-2013 distribution, and I use the same editor (TextMate 2.0) on both.
Could I somehow have created different LaTeX environments on each machine? How should I go about finding what causes this problem?
