Add encoding support for markdown documents instead of defaulting to ASCII

I have been successfully generating markup files with this module, and started to render them with mkdocs or hugo. Yesterday I noticed that mkdocs wasn't able to render a file due to an encoding problem:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfc in position 991: invalid start byte

I took a look at the WriteDocumentContent function and I found that it doesn't specify the -Enconding parameter of Set-Content:

$content | Set-Content -Path $Path;

According to the documentation, the default value for the encoding of Set-Content is ASCII.

My current workaround for this is to specify the -PassThru parameter of Invoke-PSDocument and write the result to disk myself with the correct encoding:

Invoke-PSDocument -Name Test -PassThru | Out-File -FilePath ".\result\Test.md" -Encoding utf8

However, if the default behavior of Invoke-PSDocument is to write content to the disk, it should either be possible to specify the encoding, or the default encoding should not be ASCII

@normvariante thanks for the feedback. We should default to UTF-8 since that is generally the default encoding markdown tools prefer and override by exception.

@Normvariante master has encoding updates to support -Encoding
