Shell Programming and Scripting

Hi,

I have a requirement to fetch the length of a line within awk. I see that wc -c returns the number of bytes consumed, which is my requirement. However, the "length" function does not return the same, when I have non-ascii characters which are more than 1 byte.

I have tried the below option, but it does not seem to work. I am working on ksh on Linux environment.

Code:

{
cmd="wc -c "StringToCheck
( cmd | getline TheCount )
print cmd
}

I have also tried using "echo -e | wc -c | getline TheCount", but the count returning is not the number of bytes.
