Got in to work this morning, and my work computer was sending files back to
my home computer - files that we already synced. It doesn't note that any
files were updated or added, it just says "Sent to.." for each file.

Here's the thing - every file it's resyncing has some sort of non-English
character in it... é or ü or ñ or ° or the like. Every one.

Just a guess, but it would seem they adjusted something to better handle
non-English characters.
