how to get the string's byte length?

Thank you,Adam Cameron

The result is 13,but not 14,why?

Sure. Change it so that it does.

;-)

for (i=1; i <= len(t); i++){

=>

for (i=1; i le len(t); i=i+1){

Thank you very much,PaulH and Adam Cameron .
I have test this string in sybase sql anywhere with this sql:
select datalength('hihi，这是测试')
the sql result is: 14
This is i wanted.

To PaulH :
i test your code with my test string,the result is:
hihi�����Dz���
cf len:=13
byte len:=13
java string length:=13
java string objectlength:=13


To Adam Cameron :
Your code result is:
[1] [104]
[2] [105]
[3] [104]
[4] [105]
[5][�][65533]
[6][�][65533]
[7][�][65533]
[8][�][65533]
[9][�][65533]
[10][Dz][498]
[11][�][65533]
[12][�][65533]
[13][�][65533]

both can not get the 14 !!!![/]

Oh for goodness sake. YES I KNOW.

I was illustrating the point that simply counting the number of characters
in a string is *not* a way of determining how many bytes it occupies. The
OP's string, Adobe's facsimile of that string, my facsimile of /Adobe's
facsimile/ of that string; *a string*.

There *must* be some way of calling a function thus:

int specialGoodFunction(String s);

Which returns the number of bytes the string (in whatever encoding it is)
occupies. Which is what the OP is actually interested in. Not you finding
straw men to assault for some silly reason.

Whilst checking out characters' byte lengths, I found this site: http://www.fileformat.info/info/unicode/char/search.htm, which is good for looking that sort of thing up.

Just FYI.

why do you think that string's length is 14?

<cfprocessingdirective pageencoding="utf-8">
<cfscript>
t="hihi，这是测试";
jText=createObject("java","java.lang.String").init(t);
b=t.getBytes();
writeoutput("#t#
<br>cf len:=#len(t)#
<br>byte len:=#arrayLen(b)#
<br>java string length:=#t.length()#
<br>java string objectlength:=#jText.length()#");
</cfscript>

all methods return "9".
