No, Halnote supports MSX-JE. It's not the same thing. It's same for MSX-View.
Japanese Wiki is lying???
Look the font-drivers for DM-System2.

Hanote handles Kanjis differently.
There is also a different driver for National FS-4600F, Panasonic FS-A1FM and Panasonic FS-CM1 who also have a non-standard Kanji-ROM.
You are probably right, MSX-JE is not mentioned on this interesting page:

What is known about Sanyo PHC-70FDA?
I recently bought a Sanyo PHC-70FD and apparently it has a slightly different label indicating an extra A. I have not received the machine yet but I was wondering what the difference is to the PHC-70FD we all know. It could be a revised edition with Sanyo applied audio fix?
Ehmm ... maybe the Japanese stickers on some keys????
Have you asked the seller if he knows what's different?
No there is no communication of course with the seller.
If it does have an audio fix it would be really interesting to document the modifications made!
I will check the machine when it gets here (probably next week).
