Hey Cliff, That's actually not a character encoding issue. The '?' or an empty box is commonly displayed whenever a glyph associated with a character value is not available. Meaning the client doesn't have the necessary font. Also meaning, whatever editor was used to input those single quotes didn't input the more common ASCII single quote character value of 0x27. If you hexdump that content you'll see it's something else (it will probably be a multibyte UTF-8 secquence which when decoded will give you a Unicode value that you can lookup in Adobe's glyph tables). This is the sort of thing that happends when you create some content with a word processor and then copy and paste it into the web page. The way to fix this problem is to just seek and destory all of those characters and replace them with their more common equivalent values (e.g. the single quote 0x27 ASCII value). Or you could install whatever wacked out font that has that character on every client that will ever visit the page but that's probably not the more desirable solution. > In phpMyAdmin I see: can't > In my app, I see: can?t > So phpMyAdmin is displaying things correctly on either platform. That's odd. Maybe phpMyAdmin is doing some transliteration. > Where should I start looking? What is the best charset to use anyway? > Iso-8859-1 or utf-8? Look at the page with hexdump to see verify what the encoding is and what the unicode value of one of the errant characters really is. Then you can start to figure out where things went wrong.
