Nit: Why not just ASCIIToUTF16() instead of converting both to wide?

Also, frankly, I'd probably prefer to just write EXPECT_XX(ASCIIToUTF16("foo"),
...); than use these macros, but whatever.

[oshima, 2011/01/20 21:35:48]

Scott suggested to use this in order to be able to print the string as readable
string when check failed because string16 is printed as { 0x80, ... } instead of
"abc" on linux.

I added comment in the original cl.

Then we should write an appropriate operator<<() for string16.  Otherwise
everyone everywhere suffers from this problem.

Can you either fix this or file a bug on doing so, and note that we should
remove all these kinds of macros when we fix it?
