About Config Editor unicode 
### Current Situation

There are some problems happend when I used Homebridge Config Editor ,I need plugin output Hex format , but if I add \x to JSON string and SAVE, it will be saved by unicode format, so plugin indeed output wrong hex.
e.g.  JSON str is \xFD ,output is 0xC3 0xCBD
what should I do for fix this problem , I try to change PATH for disable unicode but it failed.
