Description DaeHyun Sung 2019-01-30 16:46:31 UTC
Description:
Can't combine Korean Hangul Final Consonant on specific Hangul Syllable '가'in LibreOffice Impress.
But, the others Hangul Syllable works in LibreOffice Impress.

example) 반갑습니다
actual) 반가ㅂ습니다
expected) 반갑습니다

only mix Korean Hangul Final Consonant with specific Hangul Syllable '가'.

Steps to Reproduce:
Input Korean Hangul Syllable '갑'
1. ㄱ
2. ㅏ
3. ㅂ

Actual Results:
가ㅂ

Expected Results:
갑 


Reproducible: Sometimes


User Profile Reset: No



Additional Info:
If you add Korean Hangul Final Consonant on Korean Hangul Syllable "가" , It can't combine Hangul syllables on LibreOffice Impress
Example)
각 > 가ㄱ (ㄱ + ㅏ + ㄱ)
간 > 가ㄴ (ㄱ + ㅏ + ㄴ)
갇 > 가ㄷ (ㄱ + ㅏ + ㄷ)
갈 > 가ㄹ (ㄱ + ㅏ + ㄹ)
감 > 가ㅁ (ㄱ + ㅏ + ㅁ)
갑 > 가ㅂ (ㄱ + ㅏ + ㅂ)
갓 > 가ㅅ (ㄱ + ㅏ + ㅅ)
강 > 가ㅇ (ㄱ + ㅏ + ㅇ)
갖 > 가ㅈ (ㄱ + ㅏ + ㅈ)
갗 > 가ㅊ (ㄱ + ㅏ + ㅊ)
갘 > 가ㅋ (ㄱ + ㅏ + ㅋ)
같 > 가ㅌ (ㄱ + ㅏ + ㅌ)
갚 > 가ㅍ (ㄱ + ㅏ + ㅍ)
갛 > 가ㅎ (ㄱ + ㅏ + ㅎ)
But, default Impress template format is correctly done.

I tested it on openSUSE Tumbleweed and KDE Plasma Desktop and fcitx-hangul(IME).

Hi DaeHyun,

Can you paste the information list in "Help / About" here?
Also I wonder if 6.0 series has the same bug? Knowing the earliest version that the issue is reproducible allows bibisecting the issue. Other QA people might help but it really needs knowledge of Korean language.

I have no knowledge about Korean IME, it will be good if you can explain how to enter the following symbols fcitx-hangul ( or how to use that IME, to the extent just enough for reproducing that issue ):
1. ㄱ
2. ㅏ
3. ㅂ

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.

Hello DaeHyun Sung,
Does it work if you launch LibreOffice from commandline with SAL_USE_VCLPLUGIN=gtk soffice ?
