This test case uses String.quote(), because that method uses the JS printf()
functions internally. The printf() functions print to a char* buffer, causing
conversion to and from UTF-8 if UTF-8 is enabled. If not, UTF-8 sequences are
converted to ASCII \uXXXX sequences. Thus, both return values are acceptable.
