Hi guys,
I’m looking for mp4 player which support viewing of Japanese TXT file
Player I’m thinking of buying if it support viewing Japanese TXT are
“Gemei X750”, “Ainol V2000”, “Oppo Luna V5” and maybe upcoming “Hacha PA20 or PC20”
If anyone is kind enough to let me know whether above players support Japanese TXT file,
or any other player in the market, I would be very much appreciated.

Thanks!
