Character Escape Sequences
Several
ybload
and ybunload
options support the following
escape sequences as option values: \t
: tab\b
: backspace\n
: newline\r
: carriage return\f
: formfeed\'
: single quotation mark\"
: double quotation mark\\
: backslash\0
: null byte\us
: ASCII unit separator\rs
: ASCII record separator
You can specify these escape sequences as shown in this list, or you can use the equivalent hexadecimal or Unicode escape sequences.
Hexadecimal escape sequences must start with 0x
(lowercase
x
). Any number of hex digits may follow. Unicode escape sequences start
with u+
or U+
. The capitalization and number of hex digits
are both flexible: u+1f
, U+01F
, and
u+001F
are all equivalent.
The following table shows two examples. The three escape sequence columns show how you
would specify the values in a ybload
or ybunload
command.
The ASCII decimal values are shown for reference; you cannot specify these values in the
command.
