This error cannot specify one version.
(But I put it up to 1.19 because I had to register the version once.)
This is because this error has been made since the first Korean language was supported, and it has not been resolved until now.
An error that can be found from the old to the latest version.
I wonder why it hasn't been solved so far.

There is a font texture error.
The part C70C to C713 of unicode_page_c7 is incorrect.
In this part, it should be written as '윌윍윎윏윐윑윒윓', but somehow, it's written in the same letters from C6D4 to C6DB in unicode_page_c6.

This is a problem that can cause inconvenience to Korean players.
They have a problem that they can't type the word "윌" even if they want to type it, and they only type the word "월".
This is a serious problem, so please solve it as soon as possible.

This is a problem with the Java version.
If the font file was used in the Bedrock version, it could be a problem in the Bedrock version.

I uploaded the font that shows the error in the attached file.
The part marked in red is the wrong part, and the part marked in blue is a comparison photo to show the same part as the wrong part.

(I am not good at English, so I used a translator.)
