Description:
When typing asian characters, i'm unable to type any punctuation marks such as: spaces, commas(,), periods(.), quotation marks("), and, additionally, backspace also does not work. the only way to type such punction marks is to press ESC, which converts typing mode to english. 

Steps to Reproduce:
1. open libreoffice writer.
2. set default language to korean.
3. change input mode to korean (you should be using korean compatible layout. normally it's called 한/영 key (korean/english key) and bound to right alt key.
4. write any korean.
5. while still in korean mode, try to type any non-korean key, such as: punctuation, spaces, or backsapces.

Actual Results:
on korean mode, it is impossible to type any punctuation mark or spaces or backspaces. only korean characters are typeable.
when pressing ESC, it automatically reverts to english. this is problemetic since any accidental ESC means another 한/영 key to switch to korean.

Expected Results:
input mode should not prohibit user from typing non CJK letters.
in other words, in asian text mode, user should be able to freely type backspaces, spaces or other punctuation marks.
in other words, user should be able to freely type punctuation marks whenever it's asian or non-asian.
