This is my complete command, which accepts the wrap_unicode option, but the option is not working

'/usr/local/ffmpeg/bin/ffmpeg' '-y' '-i' 'input.mp4' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'aac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-vf' '[in]subtitles=test.srt:wrap_unicode=1:force_style='''FontSize=12,FontName=Angsana New,PrimaryColour=&H00FFFFFF,BorderStyle=1,Outline=0.5,Shadow=1,MarginV=50'''[out]' '-pass' '1' '-passlogfile' '/var/folders/xh/0xpfqmh57hb12ffvs5wy1v0w0000gn/T/ffmpeg-passes66e24b16ea0aa/pass-66e24b16ea47b' 'output.mp4'

Before that, I compiled libunibreak, libass(0.17.0) in order, and reinstalled ffmpeg.

I hope someone can help me understand where the problem caused this option to not take effect, this problem has been bothering me for some time, thank you very much!
