How do search engines handle special characters in code?

Using Dreamweaver, to tab a sentence, I'm using      

There are times when I look at the source code in the cache of search engines and I'm seeing "�����" .
Now if thats next to a word, I'm thinking it will change the results in the searchs. am i right on that?

Multiple spaces are going to be treated as a single space for indexing purposes.

SE should treat these as multiple spaces that will be compacted to one for indexing of data and snippet showing in preview - elements of HTML formatting play no part for snippet creation and will matter only for HTML cache data.
