+	// will take in UTF-8 by replacing a 2 byte character with 2 *'s, etc, and counting that.
+	// Note, surrogate (\uD800-\uDFFF) characters are counted as 2 bytes, since there's two of them
+	// and the actual character takes 4 bytes in UTF-8 (2*2=4). Might not work perfectly in
+	// edge cases such as illegal sequences, but that should never happen.
+
+	// https://en.wikipedia.org/wiki/UTF-8#Description
+	// The mapping from UTF-16 code units to UTF-8 bytes is as follows:
+	// > Range 0000-007F: codepoints that become 1 byte of UTF-8
+	// > Range 0080-07FF: codepoints that become 2 bytes of UTF-8
+	// > Range 0800-D7FF: codepoints that become 3 bytes of UTF-8
+	// > Range D800-DFFF: Surrogates (each pair becomes 4 bytes of UTF-8)
+	// > Range E000-FFFF: codepoints that become 3 bytes of UTF-8 (continued)
