Incredible: if you voice-dictate a message about adult chuck-e-cheese alternative Dave & Busters into iMessage, it gets flagged as a potential hacking attempt by the other iMessage client and never arrives. Because the voice-to-text detects it as a known phrase with a special typography (with the "&", not "and"), but the substitution is happening at the wrong layer and so it gets encoded as a raw '&' in the message HTML rather than an '&'. The other end correctly detects malformed HTML and panics.
Presumably, you could also run into this problem with other brands such as Simon & Schuster.
