Japanese JIS keyboard yen key option
Option to send VK_OEM_5 or appropriate virtual key for backslash when pressed yen key on Japanese JIS keyboard instead of VK_PACKET.
On mac JIS keyboard, when we press yen key, yen code (U+00A5 or c2 a5 as utf-8) is entered. To enter backslash, we use opt + yen key.
When we connect windows server under this key assignment, windows server looks recognizing yen key as c2 a5 (VK_PACKET) and opt + yen key as 1b 5c(VK_MENU with altDown and VK_PACKET with altDown?).
As the result, we are not able to enter path separator using JIS keyboard.
(on applications not ignoring "1b") I could not find workaround for this.
Historically on the DOS, a backslash was shown as a yen. It makes this confusion.
