Version: 6.1.4.2
Build ID: 9d0f32d1f0b509096fd65e0d4bec26ddd1938fd3
CPU threads: 8; OS: Linux 4.20; UI render: default; VCL: kde4;

also other version shows the same bug (openSUSE tumbleweed default version)

If you want to input the Korean Syllable '갑'(code point: U+AC11)
step1. Input the Hangul Consonant 'ㄱ'(code point: U+1100)
step2. Input the Hangul Vowel 'ㅏ'(code point: U+1161)
step3. then, Input the Hangul Consonant 'ㅂ'(code point: U+1107)

step1 & step2 is normal working.
but, In Korean IME,  step3 check step2, If step2 is vowel or consonant.
If step2 is vowel then step3's consonant change the code point (Final Consonant
code point: 'ᆸ' U+11B8)
But, In step2 is not vowel, then step3's consonant not change it and shows
Consonant 'ㅂ'(code point: U+1107) -> That's  LibreOffice's situation

I think, LibreOffice interferes with checking the process of confirming whether
consonants are initial consonants or final consonants in Korean IME .



------

fcitx-hangul is based on libhangul library.
libhangul repository: https://github.com/libhangul/libhangul

Below is libhangul example link. (GNOME Korea git repository)

That link is last year's GNOME Korea meetup slide. (Summary of Korean Hangul
Input processing)
https://www.slideshare.net/gnomekr/20180519-hangul-processing

Many of Korean IME is based on libhangul library.

If I have a time, I'll summarize and write the Korean IME working  English
version document.
