System.useCodepage is false (the default), the character is replaced by one or more

hexadecimal escape sequences of the form

%xx%xx (double-byte), and characters 2048 and

above are encoded as

%xx%xx%xx (triple-byte).

•If

System.useCodepage is true and the system is not an Asian language double-byte sys-

tem, the character is replaced with a hexadecimal escape sequence

%xx, where xx is the

hex code point for the character. The code point is determined using the system code

page (typically Latin 1 on most Western computers). Note that on Macs, the system
