Please elaborate. Possibly an example could help.

I think I understood it. Please see Solution 1.
"Byte level" is totally confusing. .NET characters are not bytes.

The concept of "stop word" is not properly defined. Proper definition should take into account not just the word itself, but its context. In your case, it can be quite simple. So, it should be not just a word, but some rule. I would advise to use Regex instead. Your "stop words" will be not just strings, but the rules of matching expressed in the form of Regular expression patterns.

Please see:
https://en.wikipedia.org/wiki/Regular_expression[^],

See also: https://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex.replace%28v=vs.110%29.aspx[^].

I don't know your rules, so you should better learn Regular Expressions and formulate what are your "stop word" by yourself.

Good luck.
