I have checked various browsers whether they accept 127, 128, 159, 160 and 384 character codes. 127 is rejected by all browsers as expected. WebKit and Opera works the same way, accepting everything else. Firefox does not accept 128, but accepts 159 and 160. InternetExplorer 8 does not accept 159, but accepts 128 and 160. The spec says characters between 127-159 should not be accepted. This is non-conclusive. IMHO we should keep the current behaviour.
