Check LRF attached.
Font implement is not done yet in PRS-700. But, you can convert chinese TXT to LRF using Japanese made ChainLP program.
Save your chinese txt to UTF-8 encoding, and convert it to LRF with ChainLP. ChainLP makes txt into image and convert it into LRF. Before binding it, you can edit it, like font, font size, margine, line size etc.
You can find this program at
