* The White-space characters separate syntactic constructs such as names and numbers from
|
|
* each other. All white-space characters are equivalent, except in comments, strings, and streams. In all other
|
|
* contexts, PDF treats any sequence of consecutive white-space characters as one character.
|
|
*
|
|
* The CARRIAGE RETURN (0Dh) and LINE FEED (0Ah) characters, also called newline characters, shall be
|
|
* treated as end-of-line (EOL) markers. The combination of a CARRIAGE RETURN followed immediately by a
|
|
* LINE FEED shall be treated as one EOL marker. EOL markers may be treated the same as any other white-
|
|
* space characters. However, sometimes an EOL marker is required or recommended—that is, preceding a
|
|
* token that must appear at the beginning of a line.
