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.
