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.
