The underlying problem is that there is no one "Extended ASCII". There's a dozen or so different schemes for the 129-255 range, all of them incompatible. That's why Unicode now exists. :-) I've been tracking this issue myself on my blog, which may be of background use for you (especially some of the pages I link, which give more theoretical background): http://www.garfieldtech.com/blog/stupid-quotes http://www.garfieldtech.com/blog/more-on-stupid-quotes http://www.garfieldtech.com/blog/unicode-8-vs-16 Odds are that the pages you're scraping are saved as ISO 8859-1, but actually contain Windows-1252. If you try to save Windows-1252 as UTF-8, then the characters in the extended range (129-255) will get mangled. You may find this useful: http://us.php.net/manual/en/function.mb-convert-encoding.php It is frequently reasonably good at guessing the incoming character set, at least the one time we used it at work. Try running all pages/strings through that first before sending them to the database to convert everything to UTF-8. You should also make sure that not only is the MySQL connection set to UTF-8, the tables and columns themselves are, too. MySQL lets you vary the encoding by table and field, so you should check to make sure that *everything* is UTF-8 explicitly. Cheers. PS: The free copy of php|architect from php|tek had a really good article on Unicode. Even if you don't read anything else from that issue, read that. :-) On Monday 11 June 2007, Richard Lynch wrote: > This may actually be a MySQL question... > > Or not. > > I'm scraping about 55,000 pages from a website into a MySQL database. > > Some of these pages have "extended ASCII" values in their content, or, > in some cases, just plain junk ASCII values, as far as I can tell. > > For example, decimal 163 is sometimes used to represent the UK > monetary symbol for a Pound. > > Unforunately, when I insert/update the text into the database, the > text is chopped off, as far as I can tell, at any extended ASCII > value. > > Now, I've set things up for UTF-8, expressly to avoid this kind of > problem, I thought: > > var_dump(mysql_get_server_info($connection)); > var_dump(mysql_get_client_info()); > var_dump(mysql_client_encoding($connection)); > > string(10) "5.0.26-log" > string(6) "5.0.26" > string(4) "utf8" > > I'm open to any advice about the correct solution to convert "extended > ASCII" as typed in emails by tens of thousands of users on diverse > systems, from diverse countries... > > Note that "extended ASCII" is inconsistent from Microsoft to Apple to > Unix to ..., as far as I understand it, so I really can't be sure > which charset the original user was using. > > Of course, for now, I'll just change any extended ASCII into space and > move on with life...
