The solution, however, is extremely simple: when creating and/or editing server-side files (such as those used with WordPress) be sure to only ever use a purpose-built. The problem here is that word processors need to embed a lot of extra data in the file (behind the scenes) in order to define various things like font styles, etc - data that is almost always both specific to the word processor being used AND completely incomprehensible to the kind of server-side systems required to run websites (be them powered by WordPress or otherwise). One of the most common mistakes WordPress-newbies make is using a word processor (like Microsoft Word, Pages, and WordPerfect) to edit server-side source-code files (such as.html.css and.php files, etc).
