A possibly related issue:
I use autohotkeys (AHK, a replacement for the venerable AllChars) to expand short strings into longer ones, like say an email address:
]jg => Joseph.Something@gmail.com
AHK is extremely useful in that it can do a lot more than this simple example, so I use it a lot.
For example, to enter date and time I use ]dt which expands to 4/2/2020 2:47 PM.
However, when remoting in with RU, it does not transmit the upper case or shift, so that the email example becomes
joseph.something2gmail.com
While an email address is not case-sensitive, the @ becomes 2 (the lower case for that key), which makes it unusable.
The date & time in RU expands to 4/2/2020 2;49 PM which is also incorrect.
If I remote from the same laptop to the same host machine via other remote software like UVNC, [censored] , or RDP, this does not happen. The string expansions happen correctly. In fact, I can simultaneously remote into the host machine via RU, UVNC, and [censored] , to try the expansions into the same program like Notepad, and the problem only happens with RU.
I have tried the RU settings for Scan code and Unicode, and they make no difference.
Any ideas?
