--- Comment #7 from JO3EMC <jo3emc at jarl.com> ---
As you may know, in the current Japanese language, LTR is the basis for
horizontal writing.
So, no matter what the automatic language group selection works, you usually
don't have to worry about mixed character directions.

Of course, sentences with a mixture of Western characters (mainly English ASCII
characters) and Japanese characters are common.
In such cases, it is natural that the Western characters are treated as Western
instead of Japanese.
The current automatic recognition of LibreOffice language groups seems to work
well in the Japanese environment.
So I don't think we'll often encounter cases where we have to manually change
language groups individually.

ASCII numerical characters are also automatically recognized as Western.
In Japanese, that is OK.

As discussed in Bug 146910 etc., there is some need to apply the same font to
both Western and CJK language groups, but that is not the same as wanting to
treat them all as the same language group.
It is a need to recognize them as different language groups and to be able to
easily apply the same font.
There are also many needs to apply different fonts to each.

So far, I've talked about the situation in Japanese that seems to be related to
this issue, but I haven't fully understood this issue.
I'm unfamiliar with CTL and RTL and can't figure out what's wrong and how you
want it to work.
Please pardon.
