QSF Character Test Page

illegal?<> etc just encodes the illegal chars! But probably doesn't pass well formed test?
<> and grave accent encoded; pipe corrupted to ':' when on local system, ok online
QGV returns |{}^`, ignoring the <> when in html mode, but giving them correctly in plain text mode!

great selection of reserved: !$+,:=?~*' only the last, the apostrophe, is encoded to %27!
QGV returns: !$+,:=?~*'

two brackets: () [] ok in firefox.
QGV returns ()[], so OK!!
