    ECMA Section:       Source Text
    Description:

    ECMAScript source text is represented as a sequence of characters
    representable using the Unicode version 2.0 character encoding.

    SourceCharacter ::
    any Unicode character

    However, it is possible to represent every ECMAScript program using
    only ASCII characters (which are equivalent to the first 128 Unicode
    characters). Non-ASCII Unicode characters may appear only within comments
    and string literals. In string literals, any Unicode character may also be
    expressed as a Unicode escape sequence consisting of six ASCII characters,
    namely \u plus four hexadecimal digits. Within a comment, such an escape
    sequence is effectively ignored as part of the comment. Within a string
    literal, the Unicode escape sequence contributes one character to the string
    value of the literal.

    Note that ECMAScript differs from the Java programming language in the
    behavior of Unicode escape sequences. In a Java program, if the Unicode escape
    sequence \u000A, for example, occurs within a single-line comment, it is
    interpreted as a line terminator (Unicode character 000A is line feed) and
    therefore the next character is not part of the comment. Similarly, if the
    Unicode escape sequence \u000A occurs within a string literal in a Java
    program, it is likewise interpreted as a line terminator, which is not
    allowed within a string literal-one must write \n instead of \u000A to
    cause a line feed to be part of the string value of a string literal. In
    an ECMAScript program, a Unicode escape sequence occurring within a comment
    is never interpreted and therefore cannot contribute to termination of the
    comment. Similarly, a Unicode escape sequence occurring within a string literal
    in an ECMAScript program always contributes a character to the string value of
    the literal and is never interpreted as a line terminator or as a quote mark
    that might terminate the string literal.
