Size of a unicode string

[gadu]

Hello

Someone know how i can find out the size of a unicode string?

Unicode string is a bin data?

Thanks

There should be always be a strlen() type of function for your unicode strings.

strlen() is just for ANSI caracters


I need something that give me the size of some unicode string
Thanks

If you're using standard wchar's, then strlen() is called wcslen(). If you're using other kinds of wide characters, then that library/header will define a strlen-type function called ... something. Presumably you know what library/header you're using.

What you use depends on what your string is encoded as. What encoding are you using? ("Unicode" is not a valid answer.)

For UTF-8 string that are nul terminated, strlen() will return the length, in bytes, of that string.
(On Windows, you're likely dealing with UTF-16, if you're using Unicode, and tabstop's method should work.)

Perhaps. But perhaps not.
UTF-8 is very much variable length and as such, it can return incorrect length because some characters span several bytes. Unicode is a tricky topic.
