In the case addressed by the referenced bug, the string was used in a
call to Append, which meant that this is still inefficient. The patch in
the bug fixed this by switching to appending a character rather than a
string.
If you do need to append a wide string rather than a character you have
the choice of s.Append(NS_LITERAL_STRING("stuff")) or
s.AppendLiteral("stuff"), both of which measure the length of the string
at compile time, unlike s.Append(MOZ_UTF16("stuff")) which measures it
at run time. As of bug 514173 I hope to make
s.AppendLiteral(MOZ_UTF16("stuff")) work too. (I can't overload Append
because I can't guarantee that you're really passing a literal.)
