Hello guys,

Im using insanely-fast-whisper to transcribe some audios in chinese (original audio in chinese as well). Then I used the convert_output.py to convert the json to srt, but Im getting this error.

File "C:\Users\xxx\convert_output.py", line 101, in
main()
File "C:\Users\xxx\convert_output.py", line 96, in main
convert(args.input_file, args.output_format, args.output_dir, args.verbose)
File "C:\Users\xxx\convert_output.py", line 67, in convert
data = json.load(file)
File "C:\Program Files\Python310\lib\json_init_.py", line 293, in load
return loads(fp.read(),
File "C:\Program Files\Python310\lib\encodings\cp1252.py", line 23, in decode
return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 128: character maps to

any help? thanks
