Spaces are converted to invalid characters

The output is:

ￂﾠￂﾠ/@

While it should be:

@

In debug mode, it outputs the same box characters.

Actually, I wonder if this is a PyPy.js bug. Code on my side seems to be OK. The data is being sent in from PyPy.js with those weird escape sequences.

This bug is worth an explanation! The spaces in the input box were converted to non-breaking spaces by jQuery, which completely killed the regex matcher. It seems the monospace font doesn't have support for the non-breaking spaces, so they came up as empty boxes.

I. Hate. Unicode.
