Update 230209: "Hanging Execution Sign" has been fixed. Other strings I pointed out are still there. Found one more inconsistent translation.

Update 230413: I found that "Cherry Hanging Sign"(added after the fix) is translated to "Cherry Hanging Execution Sign"(체리 교수형 표지판). Should be "벚나무 매다는 표지판".

Update 230504: Some strings are fixed. I marked them with strikethrough.

Update 241111: Only "Cherry Hanging Execution Sign" is fixed, and now only that string uses "벚나무" while other strings uses "체리나무" for "Cherry".

I am a ko_KR (South Korean) proofreader of Java Edition.

The new experimental item "Hanging Sign" is now translated in ko_KR.
The translated word is "교수형 표지판" where 교수형 means 'hanging execution' and 표지판 means 'sign'.

For those who are interested but don't know Korean, 교수형 is written 絞首刑 in Chinese characters. Each letter literally means: 'hang', 'head', and 'punishment'. This word only means the 'hanging execution', not general 'hanging'.

This translation must be from Bing translator. Google translator also translates this wrong, but in a different way. (More like, "Hanging Execution Mark") Papago translator yields a more correct translation: "매달린 간판"(Hanging [storefront] Sign). We have seen many Bedrock translations that are just copied from Bing translator.

I suggest that Bedrock use "매다는 표지판", which Java Edition uses.

And please fix "Bamboo Mosaic Slab" => "대나무 모자이크 슬래브" too. Bedrock translates 'Slab' to '판', so "Bamboo Mosaic Slab" should be translated to "대나무 모자이크 판".
