I've managed to mostly ignore all this multi-byte character stuff, but now I need to do some UI work and I know my ignorance in this area is going to catch up with me! Can anyone explain in a few paragraphs or less just what I need to know so that I can localize my applications? What types should I be using (I use both .Net and C/C++, an...
I'm trying to use P/Invoke to fetch a string (among other things) from an unmanaged DLL, but the string comes out garbled, no matter what I try.
I'm not a native Windows coder, so I'm unsure about the character encoding bits. The DLL is set to use "Multi-Byte Character Set", which I can't change (because that would break other project...
Today I ran into a problem with the php function strpos(), because it returned FALSE even if the correct result was obviously 0. This was because one parameter was encoded in UTF-8, but the other (origin is a HTTP GET parameter) obviously not.
Now I have noticed that using the mb_strpos function solved my problem.
My question is now: I...
Does the term multibyte refer to a charset whose characters can - but don't have to be - wider than 1 byte, (e.g. UTF-8) or does it refer to character sets which are in any case wider than 1 byte (e.g. UTF-16) ? In other words: What is meant if anybody talks about multibyte character sets?

EDIT: the script mentioned in the question, and the other script pointed among the answers, both work just fine with multibyte strings - turned out my problem was elsewhere.
Does anyone know of such implementation? The script at http://phpjs.org/functions/view/469 works well, just not on multibyte strings.

If I write:
rename('php109.tmp','test.jpg');
then it's fine and working.
but if I change it into:
rename('php109.tmp','中文.jpg');
it'll report "No such file or directory...".
But the multi-byte characters can be written into database then read out fine,
why it fails when towards rename ?

currently I listen on "Enter" key to start sending a message,
But for multi-byte characters,the "Enter" key is supposed to choose a certain character.
The problem is that I've no idea how to detect whether a user is in the middle of inputting
a multi-byte character,and even if he's in that process,the message will be sent the first

Where can I get a complete list of all multi-byte functions for PHP? I need to go through my application and switch the non MB string functions to the new mb functions.

Hi there!
As we all now, handling multibyte strings is not that easy in PHP. For example I want to get the length of the following string: ä
strlen('ä'); // 2, because ä equals 2 bytes
mb_strlen('ä', 'UTF-8'); // 1
iconv_strlen('ä', 'UTF-8'); // 1
Which functions should I use? The mb_* or iconv_*? Why? Considering that the encoding ...
(Sorry if a newb question...I've done quite a bit of research, honestly...)
I'm writing some Ruby on Rails code to parse RSS/ATOM feeds. My code is throwing-up on on a pesky '£' symbol.
I've been trying the approach of normalizing the description and title fields of the feeds before doing anything else:
descr = self.description.mb_ch...
I have a multi-byte string containing a mixture of japanese and latin characters. I'm trying to copy parts of this string to a separate memory location. Since it's a multi-byte string, some of the characters uses one byte and other characters uses two. When copying parts of the string, I must not copy "half" japanese characters. To be ab...
I tried:
mb_strlen('普通话');
strlen('普通话');
both of them output 9,while in fact there are only 3 characters.
What's the right way to count characters?

For example,both , and , are commas,but the first one takes 2 byte,while the second one only 1.
How to convert the 2 byte one to 1 byte?

Try this:
$pattern = '/[\x{ff0c},]/u';
//$string = "something here ; and there, oh,that's all!";
$string = 'hei,nihao,a ';
echo '<pre>', print_r( preg_split( $pattern, $string ), 1 ), '</pre>';
exit();
output:
<pre>Array
(
[0] => hei,nihao,a
)
</pre>

I'm working with JasperReports 3.6 and trying to create a report with the PDF format which will meet our customer's needs.
By exporting to PDF, I found that multi-byte characters (Japanese/Shift-JIS, EUC-JP, UTF-8, ISO-2022-JP) would be printed in the newline automatically without setting the "/n" code.
The field would be expected to s...
echo '<a title=' .json_encode("按时间先后进行排序") . '>test</a>';
The above will generate something like "\u6309\u65f6\u95f4\u5148\u540e\u8fdb\u884c\u6392\u5e8f" and it's a mess!

Normally I would just do this.
$str = preg_replace('#(\d+)#', ' $1 ', $str);
If I knew it was going to be utf-8 I would add a lowercase "u" modifier to the pattern and I think I would be good. But because of reports of utf-8 taking 2x and in some cases 3x the storage space than it would take if the native character set were used, I'm ...
The unicode standard has enough code-points in it that you need 4 bytes to store them all. That's what the UTF-32 encoding does. Yet the UTF-8 encoding somehow squeezes these into much smaller spaces by using something called "variable-width encoding".
In fact, it manages to represent the first 127 characters of US-ASCII in just one...
$str = "This is a string containing 中文 characters. Some more characters - 中华人民共和国 ";
How do I detect chinese characters from this string and print the part which starts with the first character and ends with "-"? (it would be "中文 characters. Some more characters -").
Thank you!

I want to conform my site's string handling to support other languages per UTF-8. It seems that the best way to do this is to forsake all the standard string functions.
So I have two options, I can set the mbstring.func_overload option in php.ini or I can go back over my code and just replace all the functions with mb_*. I would assume ...
