Why does the Windows 10 HanYu Pinyin entry method for the 亅 (hook radical) character require typing "jue3" (juĕ) instead of "jue2" (jué)?
This character is not often used in China. As a Chinese person, I don't know the character until I searched it on the internet. The electric dictionary says it should be jue(3). At last, I have to say I really didn't recognize the character. If we want to express the word "hook ", we would directly use 勾子 instead of jue (3). Hope I did help you.
I have referenced to many online Chinese Dictionaries,
basically it is "jue2" (jué), not "jue3" (juĕ).
May be the programmer or editor of the HanYu Pinyin entry method is confused by the Cantonese:
Refer to: CANTONESE
because the pronunciation of 亅 in Cantonese is kyut3
I hope I did answer your question.
