Trigraph Symbols

Trigraph is a standard for describing special characters. This standard can be used when describing characters used as separators in a file.

The table shows characters in the external file with the equivalent Trigraph symbols:

Table 1. Characters in the external file with the equivalent Trigraph symbol
Character in the External File	Trigraph Symbol
\	\\
?	\?
'	\'
"	\"
TAB	\t
Vertical TAB	\v
Alarm	\a
Clock	\b
Form feed	\f
New Row	\n
Linefeed	\r

Example:

If the file is separated using TAB-character, you cannot use the TAB key to describe this character. Instead, you have to use the Trigraph symbol \t to describe the TAB-character.
