[jdev] Re: Get the length of the utf-8 sequence in Java

[Cedric Vivier]

I do not believe Java has a standard method for this in the standard 
library, but you could implement yours :

public int byte_length(String s) {
    int numchars = s.length();
    int numbytes = 0;
    for (int i = 0 ; i < numchars ; i++) {
      int c = s.charAt(i);
      if ((c >= 0x0001) && (c <= 0x007F)) numbytes++;
      else if (c > 0x07FF) numbytes += 3;
      else numbytes += 2;
    }
    return numbytes;
}
I have no idea if it would be faster than your current method though, 
but it should be more memory-efficient at least.
