Umlaut characters / Shifted keys / Emoji mapping?

[KungPhoo]

Hi,

awesome work you did!
When polling events, and pressing Shift+2, I get event.keyboard.keyCode = 50, which is '2'.
However, I was expecting the quote '"' 0x22 code, instead.
Did I do anything wrong?
Also, the emoji keyboard in Windows has no effect. Here's how to implement that, if it helps.

        static wchar_t highSurrogate = 0;  // Store high surrogate if needed
        ReadConsoleInputW(hStdin, &inputRecord, 1, &eventsRead);
        if (inputRecord.EventType == KEY_EVENT && inputRecord.Event.KeyEvent.bKeyDown) {
            WCHAR ch = inputRecord.Event.KeyEvent.uChar.UnicodeChar;
                // Detect surrogate pairs
                if (ch >= 0xD800 && ch <= 0xDBFF) {
                    // It's a high surrogate, store it
                    highSurrogate = ch;
                    continue;
                } else if (ch >= 0xDC00 && ch <= 0xDFFF && highSurrogate != 0) {
                    // It's a low surrogate, combine with high surrogate
                    key.printable = (ch != 0);
                    uint32_t fullCodePoint = ((highSurrogate - 0xD800) << 10) + (ch - 0xDC00) + 0x10000;
                    key.code = fullCodePoint;
                    highSurrogate = 0;  // Reset high surrogate storage
                } else {
                    key.code = ch;
                    highSurrogate = 0;  // Reset in case of an unexpected sequence
                }
                break;
            }
            putToKeyboardBuffer(key);
        }

Thanks!

You are right, i never implemented shift/ctrl/alt handling in combination with a key event, because key events are for a single key.
But you can check the "modifiers" field from the keyboard event and handle the required Quotes/Umlaute characters manually.

Or better, use the keyboard event "fplKeyboardEventType_Input" instead, then the mapping should work correctly.
You can see how it works in the FPL_Input demo.

Thanks. That did the trick for me.

        if (event.type == fplEventType_Keyboard) {
            keyPress.code = uint32_t(event.keyboard.keyCode);
            // printable character
            if (event.keyboard.type == fplKeyboardEventType_Input) {
                keyPress.printable = true;
                putToKeyboardBuffer(keyPress);
                lastCharPress = keyPress;
            // key repeat
            } else if (event.keyboard.type == fplKeyboardEventType_Button && event.keyboard.buttonState == fplButtonState_Repeat) {
                if (lastCharPress.code != 0) {
                    putToKeyboardBuffer(lastCharPress);
                }
            // non printable characters
            } else if (event.keyboard.type == fplKeyboardEventType_Button && event.keyboard.buttonState == fplButtonState_Press) {
                keyPress.code = 0;
                keyPress.printable = false;
                switch (event.keyboard.keyCode) {
                case fplKey_Delete:   keyPress.code = uint32_t(KeyConstant::DEL); repeatable = true; break;
                case fplKey_F1:       keyPress.code = uint32_t(KeyConstant::F1); break;
                case fplKey_Up:       keyPress.code = uint32_t(KeyConstant::CRSR_UP);  repeatable = true; break;
                case fplKey_Down:     keyPress.code = uint32_t(KeyConstant::CRSR_DOWN);  repeatable = true; break;
                // ...
                }
                if (keyPress.code != 0) {
                    putToKeyboardBuffer(keyPress);
                    if (repeatable) {
                        lastCharPress = keyPress;
                    } else {
                        lastCharPress.code = 0;
                    }
                }
            }
        }

I started a question on StackOverflow, because I don't get any WM_xx message when I use the emoji keyboard, so keep this issue open, please.
