I recently needed to add a Content-Length header to my HTTP request forged with Network.HTTP [1]. However, this needs to be the length of the body content in bytes, not characters. Without assuming the characters will all be ASCII, is there an easy way of doing this? length seems to have the correct results, but I'm uneasy about relying on this.
Is your string a string of unicode characters, or just a string read from somewhere in some encoding (in which case the value of each character is less than 256). In former case length function will fail to give correct result if you use multi-byte encoding like utf-8. You'd need to do the conversion and only then count length of the resulting sequence. In latter case length is always good, because you really have string of bytes that encode your content in some encoding, not characters, in a way.
