[e2tox]

but insertEntity and updateEntity does.

add utf8 encoding to the contant type and get the correct string length from Buffer.byteLength().

all unit tests passed.
self tests passed.

Hi @e2tox,

Sounds like this fix would be interesting. In order for us to look at it and merge it we have however to ask you to read our contribution guidelines and, if you're ok with it, send us the form so that you can become one of our contributors:
http://windowsazure.github.com/guidelines.html

It's a one time thing and then we can accept all your future pull requests without this hassle.

Thank you,
Andre

Also, one small detail: our contributions (and ongoing development) go into dev. Could you issue the pull request against dev instead of master ? :)

Master is designed to handle released code.

Thank you,
Andre
