This does not seem to be correct. I read that utf16 can be 4 byte long..
Then calculation is needed sometimes...
Unless you're dealing with klingon and ancient languages,
Like Chinese? Just a billion people use it...not a real problem at all...
:-\
I (wrongly) thought that chines was in the bmp :-(
I think you can assume that for 99.99% of currently spoken languages every
character will be exactly 2 bytes long.
Wrong as I said before.
There's a risk of having some character with more that 2 bytes but it is
a small risk.
With utf-8 the risk is bigger, so you have always to traverse
the string if you need access to a specific character index.
You have to go through the string for UTF-8 and UTF-16 encodings
so the advantages are at least questionable...
Yes, but my (wrong) premise is that you could assume all characters are
2 bytes wide, so the Nth character would be at N*2 byte.
