     9    ECMA Section:       Source Text

    10    Description:

    12    ECMAScript source text is represented as a sequence of characters

    13    representable using the Unicode version 2.0 character encoding.

    15    SourceCharacter ::

    16    any Unicode character

    18    However, it is possible to represent every ECMAScript program using

    19    only ASCII characters (which are equivalent to the first 128 Unicode

    20    characters). Non-ASCII Unicode characters may appear only within comments

    21    and string literals. In string literals, any Unicode character may also be

    22    expressed as a Unicode escape sequence consisting of six ASCII characters,

    23    namely \u plus four hexadecimal digits. Within a comment, such an escape

    24    sequence is effectively ignored as part of the comment. Within a string

    25    literal, the Unicode escape sequence contributes one character to the string

    26    value of the literal.

    28    Note that ECMAScript differs from the Java programming language in the

    29    behavior of Unicode escape sequences. In a Java program, if the Unicode escape

    30    sequence \u000A, for example, occurs within a single-line comment, it is

    31    interpreted as a line terminator (Unicode character 000A is line feed) and

    32    therefore the next character is not part of the comment. Similarly, if the

    33    Unicode escape sequence \u000A occurs within a string literal in a Java

    34    program, it is likewise interpreted as a line terminator, which is not

    35    allowed within a string literal-one must write \n instead of \u000A to

    36    cause a line feed to be part of the string value of a string literal. In

    37    an ECMAScript program, a Unicode escape sequence occurring within a comment

    38    is never interpreted and therefore cannot contribute to termination of the

    39    comment. Similarly, a Unicode escape sequence occurring within a string literal

    40    in an ECMAScript program always contributes a character to the string value of

    41    the literal and is never interpreted as a line terminator or as a quote mark

    42    that might terminate the string literal.
