I’m not sure if this is the right place for my post, but I just purchased online the Big Book of Powershell Gotchas. Many pages (especially at the title) have typos/misprints (?) it seems, based on a few quick observations, almost always 3 characters and when the apostrophe is used. The successive characters are always lower case ‘a’ with circumflex, the euro currency symbol, and the TM superscript. Is there a correct copy somewhere?
