Here is a screenshot when I clicked on the 14.6.9 link in the table from the link I provided earlier which shows v14.6.9 is compatible with 10.15.4+......so Catalina.

You don’t mention what issue or error has occurred.

As one possibility, Apple restricts some parts of Unicode in the English forums.

Here is the Japanese forum: 公式 Apple サポートコミュニティ

As for your question, you will probably be learning about file encoding and text editor support. As ws mentioned above, BBEdit (free version) does pretty well with most files.

You will also need to write the files where you have access, such as within your login directory. If the app you are using is from the app store, you may need to enable full Disk Access for it, as well.

Some info on Mojibake, for those unfamiliar: https://en.wikipedia.org/wiki/Mojibake — that describes the issues specific to common encodings of Japanese characters.

Windows 98 (W98) character encodings are going to get you ~nowhere on other platforms, and may well also have issues on newer Windows.

Encodings were particularly an issue (again) in the late 1980s through roughly Y2K; in the era before Unicode and UTF-8 became more widely adopted. Unicode was in response to these encoding issues, as ~everybody had their own character encodings for most anything past ASCII, such as DEC MCS and its close relative ISO Latin 1, and the various Windows encodings of the era. And ASCII itself resulted from endemic character encoding issues in that earlier pre-ASCII era, what with EBCDIC and FIELDATA character encodings, among others.

You’ll want to transcode from whatever encoding you’re trying to read into UTF-8, most likely. Which means figuring out what encoding is in use. Which is not necessarily easy. Which is Mojibake here, or is whatever other equivalent for whatever other character encoding somebody is trying to parse.

It appears you can still download older versions of BBEdit that are compatible with older outdated versions of macOS.
