JavaScript: convert string to byte array?

Question

JavaScript

Actually, the task was to convert images to Base64 on the client side. It was decided to get the picture itself via XmlHttpRequest with responseType = 'arraybuffer'. And it would be all right if XmlHttpRequest 2 was implemented in IE and other ancient browsers.
So far, I can get the picture as a string, and it already needs to be converted to an array of bytes. Can anyone help? Everything I found is applicable only for strings containing only printable characters.
