Glad we got to the bottom of that. That's quite a nasty = compiler/language bug I must say. Not even a warning. Still, python crashes= when trying to print the name of a null character. It wouldn't surpris= e me if there are other weird issues lurking. Would definitely sleep better= with a more restricted character set.

Please excuse me. I had a more thorough look at the original problem and found that the only problem with the original test case was that you

\u010400 but that doesn't work.

Here is a fix for bitcoinj. The test now passes.

https://github.com/bitcoinj/bitcoinj/pull/143

We can (and probably should) still need to filter control chars, I'll have a look at that now again.
