3.3 Streams and I/O

3.3.2 New stream variables

The following extensions to Common Lisp have been added to support multiple coded character sets:

*default-external-format* *default-base-external-format*

These variables provide the default value of the:external-format keyword argument to the Common Lisp functionopen. This keyword argument names the external encoding scheme used for character I/O operations.

The initial values for these variables differ for each supported platform. The initial values for*default-external-format* are shown in Table 3.1.

Initial values for*default-external-format*
Platform Keyword Character set
HP :hp15 double-byte HP15
RS6000 :shift-jis double-byte PC932 (Shift JIS)
SunOS/Solaris :euc double-byte in EUC codeset 1

Initial values for`*default-external-format*`
Platform	Keyword	Character set
HP	`:hp15`	double-byte HP15
RS6000	`:shift-jis`	double-byte PC932 (Shift JIS)
SunOS/Solaris	`:euc`	double-byte in EUC codeset 1

The initial values for*default-base-external-format* are shown in Table 3.2.

Initial values for*default-base-external-format*
Platform Keyword Character set
HP :ascii single-byte ASCII
RS6000 :ascii single-byte ASCII
SunOS/Solaris :ascii single-byte ASCII in EUC codeset 0
