Subject: [PATCH 1/3] [fix] Add unicode support

Since `btoa` interprets the code points of its input string as byte
values, calling `btoa` on a string will cause a "Character Out Of Range"
exception if a character's code point exceeds 0xff.

This patch replaces the `btoa` with the recommended solution from MDN,
which encodes the Unicode string to the single-byte representation
before passing it to `btoa`.
