-    Returns a UTF-8 representation of the string reference as a QByteArray.
-
-    UTF-8 is a Unicode codec and can represent all characters in a Unicode
-    string like QString.
-
-    However, in the Unicode range, there are certain codepoints that are not
-    considered characters. The Unicode standard reserves the last two
-    codepoints in each Unicode Plane (U+FFFE, U+FFFF, U+1FFFE, U+1FFFF,
-    U+2FFFE, etc.), as well as 16 codepoints in the range U+FDD0..U+FDDF,
-    inclusive, as non-characters. If any of those appear in the string, they
-    may be discarded and will not appear in the UTF-8 representation, or they
-    may be replaced by one or more replacement characters.
