I adapted the fixCodePage function for use in my standalone code-page library, and while doing so I noticed a small mix-up in its implementation. fixCodePage uses the internal functions fixInput and fixOutput to actually change the input and output codepages respectively, but while fixInput is guarded by the value setInput, fixOutput isn't guarded by setOutput—it's guarded by setInput too! This seems like a mistake, unless I'm mistaken.
