+.Qq GB2312
+.Sh DESCRIPTION
+The

+encoding implements GB\ 2312-1980, a PRC national standard
+for the encoding of simplified Chinese characters. 
+.Pp
+Multibyte characters in the GB2312
+encoding can be one byte or two bytes long.
+.No GB\ 11383-1981 ( Ns
+.Tn ASCII )
+characters are represented by single bytes in the range 0x00 to 0x7F.
+Simplified Chinese characters are represented by two bytes, both in
+the range 0xA1-0xFE.
+.Sh SEE ALSO

+.Xr gb18030 5 ,
+.Xr gbk 5
+.Sh STANDARDS
+The
+.Nm GB2312
+encoding is believed to be compatible with GB\ 2312-1980.
+This standard has been superceded by GB\ 18030-2000, but is still
+in wide use.
