drop an obsolete QChar::NoCategory enum value there is no such category in the Unicode specs. the QChar::NoCategory was a subject of bugs since it was introduced. int 4.6 it's meaning was limited to mention ucs4 > UNICODE_LAST_CODEPOINT only (which is useless anyways) in order to preserve the old (wrong) behavior. fix it now for qtbase Change-Id: I630534824e071090b39772881e747c1fdb758719 Reviewed-on: http://codereview.qt.nokia.com/1584 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>

drop an obsolete QChar::NoCategory enum value there is no such category in the Unicode specs. the QChar::NoCategory was a subject of bugs since it was introduced. int 4.6 it's meaning was limited to mention ucs4 > UNICODE_LAST_CODEPOINT only (which is useless anyways) in order to preserve the old (wrong) behavior. fix it now for qtbase Change-Id: I630534824e071090b39772881e747c1fdb758719 Reviewed-on: http://codereview.qt.nokia.com/1584 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
