#59329: Firefox gets "ReferenceError: Â is not defined" in unminified moxie.js

--------------------------+-----------------------------
 In unminified moxie.js, there exists some weird Unicode characters on line
 7391, between the BinaryReader constructor fn and the call to
 Basic.extend(). In a hex editor, you can see the character bytes are
 "C2A0", which is a random Korean Hangul character in Unicode.

 In Firefox (as of the latest 117), when using Divi, this causes an
 exception when loading unminified moxie.js. Firefox's Js loader interprets
 the first byte alone as Â, and fails while loading moxie.js.

 I can replicate this in FF+Divi, but the problem does not appear in
 Chrome, Safari, or in FF when using other builders like
 Classic/Gutenberg/Elementor/Beaver. Minification strips out the problem
 bytes.

 This link, https://stackoverflow.com/a/1462039/1201409, suggests the error
 is leftover from an earlier era of encoding a nonbreaking space before
 UTF-8 replaced other encodings.

 Regardless of how the bytes got in there (and whether FF/Divi have bugs),
 they shouldn't be there, and luckily, the fix is trivial: delete them.
