[korean_rr] Space does not work at all including for combing jamos
This issue first raised on community forum here - Korean RR Keyboard space not working
You can not type a space. Or when attempting to combine jamos nothing happens. User report was for Windows version 11. Did not specify Keyman version.
Reproduced on Win 11 with Keyman 14 and 13. Reproduced on Win 10 with version 15 alpha with common core turned off.
I've tested the keyboard with Keyman 14 Stable (14.0.283) on Windows 10 Pro 21H1. The space does not seem to do the job. In Notepad, it doesn't combine the character. In LibreOffice, it doesn't separate the clusters being typed. Below is the output of "han guk" on the two apps.
Keyman 14 Stable installed from its .kmp available in the keyboard library

It looks OK on KMW though, both local build and online.
Local build:

Online KMW:

From my investigations, the JavaScript version of jamo_combine operates with this condition - "if matched length is less than two, it will simply output a space". The jamo_combine.dll does not insert a space. This is the core issue. jamo_combine.dll is used by 3 other keyboards so we need to be careful changing its behaviour.
Other issues found with this keyboard The 64-bit version of the dll needs to be built. The following dlls do not exist. show_ime.dll hide_ime.dll select_hanja.dl scroll_hanja.dll
