// ex : OEM char 'é' is returned by WScript.Shell as '‚' (Single Low-9 Quotation Mark)
// Indeed, legacy MS-DOS apps use OEM charset, i.e. code page 850 (Latin-1) on a french setup.
// In code page 850, 'é' is character 130. But as WScript.Shell use ANSI (code page 1252 on a french setup),
// it returns '‚' (i.e. ANSI character 130), that is then converted in unicode ('‚' is unicode char 8218).
//
// So to convert it back, we have to convert unicode char '‚' (code=8218) into ANSI char (code=130).
// Then we have to convert this char (code=130), viewed as an OEM char, into unicode 'é' (code=233)
