Chapter 8: Output Methods

e second method (the h line of code) uses octal codes delimited by standard paren-

theses. If we use the same text, but specify an encoding that does not use eight-bit char-

acters, such as ISO-2022-CN, there is a third possibility: pass the characters as is. See the

sixth line of the following code:

%!

/STFangsong-Light-GB-H findfont 12 scalefont setfont

100 100 moveto

<5021 4156 3D23> show

(\120\041\101\126\075\043) show

(P!AV=#) show

showpage

While the sixth line of the above PostScript program illustrates how seven-bit CJKV char-

acter codes can be passed to the show operator as is, there are some characters that need

to be escaped with a single backslash character (\) when this is done: le parenthesis, right

parenthesis, and the backslash character itself.

Output via Display

Being able to output CJKV text onto a computer monitor or other display device is a very

basic requirement in order to successfully input or otherwise manipulate text. Without

the ability to display text, imagine for a moment how you would go about processing

CJKV text. You’d be virtually blind.

A computer monitor or display screen image consists of pixels, with each pixel represent-

ing the most fundamental unit of display. In the case of monochrome displays, each pixel

can be either white or black. ese days there are better display technologies that oer
