I did run into some page talking about encoding, one guy was trying to figure stuff out on his specific issue and had success later on. There's probably more discussion on encoding than his actual issue. This thread specifically: https://www.msx.org/forum/msx-talk/general-discussion/japanese-text-encoding-standard-for-msx?page=0

Apparently the JP MSX uses a JIS X 0201 variant. Page 2 of that thread probably has the most information on it.

I'd check, but I kind of want to check Alice CD 1.03 for a content list tonight. So maybe tomorrow.
