Google Search Result Typo Or SEO Error?

I spotted a weird SEO case on Google Web Search Help forums that I thought some SEOs would appreciate looking at.

If you search for [berkshire rxinsider] in Google, Google will list two PDF files. One PDF file has the proper title tag, spelled "EasyClean" but the other one has a spelling error, "Easylllean."

The question is why?

I looked at the PDF. The text doesn't have anywhere on it the word Easylllean, it also doesn't seem to have it in the PDF files meta data - as far as I can tell. So where is Google getting the typo from?

Maybe the font the PDF is using, where the tall C looks to Google's OCR software like three Ls? Or maybe it is webmaster error and they should provide a title in the meta data of the PDF?

What am I missing?

You'd have to check out the website where the incorrect spelling originates. The search results only report what is presented by the site itself. If it's misspelled on the site, it's going to show up that way in the results.

But is he right?

Update: As mentioned in the comments, my theory on OCR being the issue seems right. An SEO uploaded the PDF to Google Docs and it converted it to text and made the same issue. You can see the output over here.
