Background

Had a client tell me that a system that was not supposed to contain duplicates, had a duplicate. Sent me an example, and, unlike other times where the font type made it appear there was a duplicate (.com vs .corn, for example), these two had all of the same characters.

I copied the characters out of the system, into an ASCII checker, and found that they were identical strings.

I attempted to find duplicates using Salesforce's reporting tools, no duplicates found.

I attempted to find both records in SOQL using a 'WHERE" check, only pulled back one of the two records.

I then started writing the above code to identify what was really going on with the strings, first by doing the basic string comparison which failed, moving to difference which said that the entire string was different, and then compareTo, at which point I lived a negative integer in the 6000s. I then decided to check character by character the unicode values. This is what led me to finally find the issue, a Zero Width, Non-breaking space character at the beginning of one of the Names.
