UTF-16 file encoding not supported

[zegardo]

When trying to tokenize a XML file with UTF-16 encoding. I'm getting this error:

System.Management.Automation.ParameterBindingValidationException: Cannot validate argument on parameter 'Encoding'. The argument "Unicode UTF-16 Little-Endian" does not belong to the set "unknown,string,unicode,bigendianunicode,utf8,utf7,utf32,ascii,default,oem" specified by the ValidateSet attribute. Supply an argument that is in the set and then try the command again. ---> System.Management.Automation.ValidationMetadataException: The argument "Unicode UTF-16 Little-Endian" does not belong to the set "unknown,string,unicode,bigendianunicode,utf8,utf7,utf32,ascii,default,oem" specified by the ValidateSet attribute. Supply an argument that is in the set and then try the command again.

I'm using a XML like this one:

<?xml version="1.0" encoding="UTF-16"?>
