.SYNOPSIS
    Script to check character encoding of workflow .xoml files found in a site collection.
.DESCRIPTION
    This script checks the character encoding of workflow .xoml files found in a site collection based
    on the security improvement documented here: https://support.microsoft.com/topic/sharepoint-2010-workflows-might-be-blocked-by-enhanced-security-policy-kb5020238-eb91e24d-eea4-4490-a281-86503adc8b27
    
    This could be altered to take an SPWebApplication object, iterate through all SPSite objects in the Sites SPSiteCollection,
    and then iterate through all SPWeb subsites in the AllWebs SPWebCollection.

.EXAMPLE
    Get-WorkflowStatusForSite -SiteCollectionUrl https://sharepoint
