8 <span>I was expecting to have to convert lots of things to be real Unicode, but nope! All that really needed to be done was to convert UTF-8 to CP437 where necessary to actually *draw* the data while keeping the internal form pure UTF-8, and then bundle everything up into a neat macro to keep everything consistent:</span>
22 <span>I just shoved this macro anywhere necessary and it works perfectly fine for loading any Unicode path. For example, the Spanish word "mañana" gets displayed correctly now:</span>
26 <span>The file sorting algorithms were a different beast though, and even now strverscmp doesn't have a real charset-independent variant. For strcasecmp, I had to implement (simple) Unicode case folding, which meant having a <a class="prettylink" href="https://github.com/schismtracker/schismtracker/blob/b858a5917ee7e83f7cb4da1ad698dd24159f241b/schism/charset_data.c#L183">switch statement that is almost 1500 lines long</a> and takes up about 20K of space in the binary.</span>
28 <span>Schism currently does not do any Unicode normalization when comparing strings. This is primarily a problem with decomposed strings (which will likely not get converted properly), though with filenames that probably shouldn't exist anyway...</span>
