I have just tried to file a bug on Thunderbird concerning a problem with its Unicode support. I included an example of the text in question; Bugzilla failed spectacularly, truncating my bug report at the first astral plane code point.

The bug report in question is https://bugzilla.mozilla.org/show_bug.cgi?id=545478.

Reproducible: Always

Steps to Reproduce:
1. Attempt to file a bug report using some text containing characters in the Unicode astral plane range --- there's an example at http://twitter.com/hjalfi/statuses/8690602802.
Actual Results:  
The bug report is truncated at the first astral plane code point.

Expected Results:  
I see the text in the bug report.

This *may* have security implications --- I don't know why it's truncating the bug report, but it smells like it's misparsing the text, and that sort of thing needs looking at closely in case it's doing something unexpected.
I shall now attempt to add the text sample in question to this bug report to see whether 'Additional Comments' fails too.
Dodgy text start: [
Yes, that truncated it as well.

My guess would be that MySQL is doing it, actually, not Bugzilla. Where in the Unicode space do these characters start?
Severity: normal → minor
Status: UNCONFIRMED → NEW
Ever confirmed: true
I've heard rumours MySQL doesn't support astral plane properly. These specific characters are MATHEMATICAL BOLD FRAKTUR from U+1D56C to U+1D59F, but I suspect it would work with anything above U+FFFF.
Ahh, do you know what version of Unicode those were added in? It may be that either Perl or MySQL aren't using that version of Unicode.
3.1.0, apparently:
