Does the Unicode Page in HID Usage Table is working in windows? RRS feed

  • Question

  • I have searched the internet and found that there is no widly used os that support this feature.

    I was making a DIY keyboard with STM32. I have implemented the standard 104 keyboard and controls of consumer devices like volume and brightness of screen. I want to add some feature that the keyboard can input some content automatically which stored in my keyboard's memory (like passwords), and I find the Unicode Page. I modified the Report Descriptor by adding a new HID report with another report id. The origin report is still work well and I can see the keyborad was sending unicode characters on host. But the windows has no response when recieved the characters.

    I want to know, if I want to input some strange characters like chinese characters which uses more than one character, what modification should I do on my keyboard's firmware?

    I don't want to develope a bran new driver for windows.
