Describe the Bug
send_unicode_string("a")
sends many keystrokes for the unicode code point of the letter a. Eg <ctrl><shift>u61<space> when it could just send a single keystroke.
This is especially noticeable when the keyboard is connected to Linux and all the extra keystrokes are briefly displayed before being replaced by the unicode character.
It makes sending macros with this function slower when the keyboard is connected to any operating system.
I believe that this could be changed directly in send_unicode_string(). If it would somehow be incompatible in some circumstances, a second function called send_mixed_string() could be introduced that would be documented to send single keystrokes for ASCII characters.
This has been implemented as a community module, but it would be desirable to have this efficiency in qmk core. See send_mixed_string.c
