Sequel Pro cannot create a JSON value from a string with CHARACTER SET ‘binary’

I had this problem dealing with exports made by Sequel Pro. I unchecked the Output BLOB fields as hex option and the problem went away. Visually inspecting the export showed legible JSON instead of binary.

导出数据的时候把 “Output BLOB fields as hex” 这个选项取消就可以了。
