Because press/release keycodes are not the same as characters. Character is produced from keycode or sequence of keycodes according to the selected kayboard layout.

Hi, Why not if the platform offers a way to simulate Unicode keyboard events? Here the platform api offers to accept decimal values or code values as input though a real keyboard may not be able to generate the same and converts it into a displayable Unicode char.

Thanks and regards,

Hi,

Are you sure that keyPress/keyRelease should emulate UTF8 symbols? Physical keyboard cannot produces so many keycodes with a single press/release.

    Hi All, Please review fix for the /_enhancement_/ wherein the
    robot key press of non-ascii were interpreted as question marks.

    Issue: The robot key press events was handling only the ascii
    inputs and ignored the other Unicode inputs. Either it was
    throwing illegal argument exception in windows or does nothing on
    the mac for those Unicode inputs.

    Solution and fix: The platform specific api’s was unable handle
    the non-ascii inputs. I have modified the api’s to accept the
    non-ascii inputs and correspondingly send the message to the
    window to print the non-ascii characters as well. Below is the
    picture of how the non-ascii inputs are considered and printed
    onto the window.

    The solution spans across windows and mac platform and still in
    search of a solution for the Linux platform. The solution
    implements key scanning only upon existing valid ascii key was
    /_not_/ found and assumes it as Unicode key and sends the event to
    event queue to be processed as Unicode keys. Different formats are
    being used by different platform implementation of Unicode. For
    ex., per the below Unicode list, in the case of windows and mac,
    the key input can take decimal values whereas on Linux it can only
    take the Code values.

    On Linux, I was able to get the KeySym of Unicode keys but was
    unable to fake the key event as there was no mechanism available
    for the same(which sends the key event to window). Please let me
    know if there is any such mechanism available to simulate Unicode
    key events on Linux platform. Hence I think to raise a bug for the
    Linux platform and close this JDK-8148344 bug.
