Hello,
Could you please review the following fix for the bug.
Bug: https://bugs.openjdk.java.net/browse/JDK-8187364
Webrev: http://cr.openjdk.java.net/~alitvinov/8187364/jdk12/webrev.00
The bug consists in the fact that on MS Windows OS with the enabled
Persian keyboard layout zero width non-joiner (ZWNJ) character, whose
Unicode code is "\u200C", cannot be entered in Swing text components
by means of "Ctrl+Shift+2" key combination. The bug does not affect
AWT text components.
CAUSE OF THE BUG:
In the method
"javax.swing.text.DefaultEditorKit.DefaultKeyTypedAction.actionPerformed(ActionEvent)"
ZWNJ character "\u200C" is not inserted to the document of
"javax.swing.JTextComponent" through the call
"target.replaceSelection(content);", because a previous call to
"sun.awt.SunToolkit.isPrintableCharacterModifiersMask(int)" method
returns "false" for the case, when key modifiers integer variable
equals 3 ("Ctrl+Shift" keys are pressed).
THE FIX:
The fix changes the method
"DefaultEditorKit.DefaultKeyTypedAction.actionPerformed(ActionEvent)"
to allow entering 2 listed below Unicode characters in the text
component's document, when these characters are treated as non-printable.
- "\u200C" - ZWNJ;
- "\u200D" - zero width joiner (ZWJ), which is entered by
"Ctrl+Shift+1" key combination with Persian keyboard layout.
Thank you,
Anton
