unicode question

Discussion in 'Programmer Misc' started by Paul Fredlein, Dec 28, 2008.

  1. Hi,

    I have a mysql database which returns, to my Cocoa app, simplified
    Chinese characters using PHP.

    The database seems to store the Chinese as double byte chars which is a
    hassle to get them in there in the first place as everything seems to
    use some kind of unicode set.

    Anyway, so far it all seems to work but I'm convinced it's just good
    luck not good management. What should I use throughout to make sure it
    doesn't break:-


    or what?

    Any help appreciated.

    You can govern which character set each table uses for storage. The
    default has changed several times over the last few versions so it's hard
    to tell which table uses each character set, but it's not hard to find out:


    Since you're a Mac user who uses MySQL I recommend the excellent
    CocoaMySQL which makes finding this out and adjusting it extremely easy.

    My recommendation is to use Unicode for everything -- either UTF-8 or UTF-16. I know it's not what you're used to but it's what the industry is moving to and it will simplify things in the long run. PHP has lots of features which use unicode internally, and do conversion to or from it when you really need to.
    Use the top one, which is the same as 'UTF-8' I referred to above.

    'gb2312' and all code pages like that are things that aren't needed any more. Unicode includes all charactersets in one encoding. Using unicode means you never have to switch charactersets just because a user has decided to use a different script -- Arabic, Tibetan, or whatever -- that you've never worried about before.
