Replace all Unicode characters with ASCII in playbook scripts

Em dashes (U+2014) and arrows (U+2192) break PowerShell 5.1 on
Windows when the file has no UTF-8 BOM -- byte 0x94 gets read as
a right double quote in Windows-1252, silently closing strings
mid-parse. This caused run-enrollment.ps1 to fail on PXE-imaged
machines with "string is missing the terminator" at line 113.
