String :Encounterring a new question

[Xwolf]

Question:How do i know the bytes of a string?

For example:

$str = "abc好abc"

NOTE:

"好" is a chinese word which have 2 bytes.

how can i get the bytes of variable $str

Thanks for everyone.

1 character = 1 byte.

so you just need to count the characters in the string.

or do something like this:

$Bin = StringToBinary("abc好abc")
$Len = BinaryLen($Bin) ;will be an integer value of 7 as there are 7 characters

Sorry,but in fact the string "好" is a word which have 2 bytes.

write it in a file and...

$o=FileOpen("test.txt",16)
$f=FileRead($o)
MsgBox(0 , "" , BinaryLen($f)-2);-2 for the @cr and @lf
FileClose($o)

btw that string is unicode andd all characters are 2 bytes so it's actually 14 bytes

No, each character is 1 byte. And if the topicstarter uses chinese chars thats his case. We can't determine if a char is chinese, korean, from outerspace or w/e... the standard is ; 1 char == 1 byte.

I think not. If you know the string is ASCII then your statement is true. But unicode characters are not one byte, and according to the help file, AutoIt supports Unicode.

I have no idea what code set outerspace uses.

and your point is? :|

try it yourself copy his string and write it in unicode and then don't even run my example use properties in windows and see what the file size is... just subtract 2 (thats the @crlf)

Thanks for everyone above.

a b c 好 a b c @CR @LF

1 1 1 2 1 1 1 1 1

1+1+1+2+1+1+1+1+1=10

Total is 10.

Am i right?

what encoding did you use ?

ansi won't recognize the char

unicode used 2 bytes for a-z and 好

and utf-8 actually uses 3 bytes for 好 and 1 byte for a-z

You could do sth like this:

;  flag = 1 (default), binary data will be ANSI
;  flag = 2, binary data will be UTF16 Little Endian
;  flag = 3, binary data will be UTF16 Big Endian
;  flag = 4, binary data will be UTF8
$Encoding = 4
$string = "abc好abc"
$Bytes = BinaryLen(StringToBinary($string,$Encoding))
MsgBox(0,"Number of bytes", $Bytes)

This returns the number of bytes depending on the encoding

Great!

A new way to deal with this problem.

Cheer!

ASCII or UFT8 ...?

In fact,i didn't know what i had used.

I just put "abc好abc" into the file test.txt .

And i found that the size of file was 8 bytes (without @CRLF).

IF i put the "enter"(with @CRLF) ,then the size of file is 10 bytes.

$string = "abc好abc"
$z1 = StringToBinary($string,4)
ConsoleWrite($z1 & @CRLF)
$z2 = BinaryLen($z1)
ConsoleWrite($z2 & @CRLF)

;Result1

Note:

The result2 was something strange.

Looking the result2 "abc好abc8"

The word "8" was behind the word "c".

In my opinion ,when i use code "ConsoleWrite($z1 & @CRLF)".

It should in this way

abc好abc
