+@node Character Encoding Record
+@section Character Encoding Record
+
+This record, if present, indicates the character encoding for string data,
+long variable names, variable labels, value labels and other strings in the
+file.
+
+@example
+/* @r{Header.} */
+int32 rec_type;
+int32 subtype;
+int32 size;
+int32 count;
+
+/* @r{Exactly @code{count} bytes of data.} */
+char encoding[];
+@end example
+
+@table @code
+@item int32 rec_type;
+Record type. Always set to 7.
+
+@item int32 subtype;
+Record subtype. Always set to 20.
+
+@item int32 size;
+The size of each element in the @code{encoding} member. Always set to 1.
+
+@item int32 count;
+The total number of bytes in @code{encoding}.
+
+@item char encoding[];
+The name of the character encoding. Normally this will be an official IANA characterset name or alias.
+See @url{http://www.iana.org/assignments/character-sets}.

+This record is not present in files generated by older software.

+
+@node Long String Value Labels Record
+@section Long String Value Labels Record
+
+This record, if present, specifies value labels for long string
+variables.
+
+@example
+/* @r{Header.} */
+int32 rec_type;
+int32 subtype;
+int32 size;
+int32 count;
+
+/* @r{Repeated up to exactly @code{count} bytes.} */
+int32 var_name_len;
+char var_name[];
+int32 var_width;
+int32 n_labels;
+long_string_label labels[];
+@end example
+
+@table @code
+@item int32 rec_type;
+Record type. Always set to 7.
+
+@item int32 subtype;
+Record subtype. Always set to 21.
+
+@item int32 size;
+Always set to 1.
+
+@item int32 count;
+The number of bytes following the header until the next header.
+
+@item int32 var_name_len;
+@itemx char var_name[];
+The number of bytes in the name of the variable that has long string
+value labels, plus the variable name itself, which consists of exactly
+@code{var_name_len} bytes. The variable name is not padded to any
+particular boundary, nor is it null-terminated.
+
+@item int32 var_width;
+The width of the variable, in bytes, which will be between 9 and
+32767.
+
+@item int32 n_labels;
+@itemx long_string_label labels[];
+The long string labels themselves. The @code{labels} array contains
+exactly @code{n_labels} elements, each of which has the following
+substructure:
+
+@example
+int32 value_len;
+char value[];
+int32 label_len;
+char label[];
+@end example
+
+@table @code
+@item int32 value_len;
+@itemx char value[];
+The string value being labeled. @code{value_len} is the number of
+bytes in @code{value}; it is equal to @code{var_width}. The
+@code{value} array is not padded or null-terminated.
+
+@item int32 label_len;
+@itemx char label[];
+The label for the string value. @code{label_len}, which must be
+between 0 and 120, is the number of bytes in @code{label}. The
+@code{label} array is not padded or null-terminated.
