mup2argmap: encoding warning

[s6mike]

Converting a argmap file into mup and then back again

e.g.

1. cat Input/Example1_ClearlyFalse_WhiteSwan_simplified.yml | lua argmap2mup > Output/Example1_ClearlyFalse_WhiteSwan_simplified.mup

2. lua mup2argmap Output/Example1_ClearlyFalse_WhiteSwan_simplified.mup > Output/Example1_ClearlyFalse_WhiteSwan_simplified_roundtrip.yml

resulted in the following differences to the original:

• Reasons and objection order reversed
• vscode warning: The character U+2019 "’" could be confused with the character U+0060 "`", which is more common in source code.
