Why some page garbled, why some garbled not garbled? A little dizzy.

Take a look at these two pages: http://www.qgren.com/qigong/gongfa/15_30.shtml
The digest appears garbled.

Look at this page again: http://www.qgren.com/qigong/gongfa/15_28.shtml
Abstract no garbled, very normal.

On the website, part of the page is normal, some page summary garbled. I'm a little dizzy.
The program is the DEDECMS,GBK version. My Web Template is also GBK.

The code for the call summary is as follows:
{dede:field.description runphp= ' yes '}
if (@me <> ") @me = '

summary : '. @me. '

';
{/dede:field.description}

Do not know who can solve my doubts, why this?

Although I see a so-called space, it may be a variation of a Chinese character.
So please check the text and tell the difference

Obviously, when you're working with text, you do the processing of replacing full-width spaces with half-width spaces.
This is the root of the problem!

Or a little garbled, people raise the amount of everyone? More than a weird stuff.

I've tried this piece of code, and I'm just wondering,
Echo str_replace (', ' \xa1\xa1 ', $s);
After this code does not output the thing,?, this strange stuff will not appear.
Conversely, as long as the back output what, such as your code, output a php_eol,?
It's so weird.
