ffmpeg drawtext use font parameter

Ask a drawtext filters question.
I import windows fonts to linux ,and draw text on video.
The text file drawtext.txt content is encoded by utf-8 no bom , the content of the textfile contain :Arabic ,Chinese, English, Korean and Japanese and etc.
When I play the result , only the Arabic and English can display normally, other text only display with some squares symbol.

./ffmpeg -y -i /data/mediadata/source/Fast.\&.Furious.7.2015.HD720P.X264.AAC.English.CHS.Mp4Ba.mp4 -filter_complex "drawtext=font=Arial:fontcolor=00ffff:x=100:y=250:textfile=drawtext.txt:fontsize=48" -t 00:02:00 out.mp4
