One thing that’s clearly missing is any sort of backup guarantee. While you may feel more secure storing your documents on Google’s or Zoho’s or Adobe’s servers than your own, that security is not something that you’re promised. Any of the three can lose your documents or terminate your ability to get to them at any time for pretty much any reason, and you’re out of luck. So if you do put important things online—back them up somewhere else.

The unicode support in Python is generally considered to be pretty good. And in comparison to many other languages, it’s good indeed.

But compared to what is provided by the International Components for Unicode (ICU) project, there’s also a lot missing, including collation, special case conversions, regular expressions, text segmentation, and bidirectional text handling. Not to mention extensive support for locale-specific formatting of dates and numbers and time calculations with different calendars.
