+.Sh DESCRIPTION
+The
+.Xr kiconv 3
+library provides multi-byte character conversion tables for kernel side
+iconv service.
+.Pp
+.Fn kiconv_add_xlat16_cspair
+defines a conversion table using
+.Xr iconv 3
+between
+.Ar fromcode
+charset and
+.Ar tocode
+charset. You can specify
+.Ar flag
+to determine if
+.Xr tolower 3
+/
+.Xr toupper 3
+conversion is included in the table.
+The
+.Ar flag
+has following values.
+.Pp
+.Bl -tag -width "KICONV_FROM_LOWER" -compact
+.It Fa KICONV_LOWER
+.It Fa KICONV_FROM_LOWER
+It generates a tolower table in addition to a character conversion table.
+The difference between two is tolower
+.Ar tocode
+or tolower
+.Ar fromcode .
+.It Fa KICONV_UPPER
+.It Fa KICONV_FROM_UPPER
+It generates a toupper table in addition to a character conversion table.
+The difference between two is toupper
+.Ar tocode
+or toupper
+.Ar fromcode .
+.El
+.Pp
+A tolower/toupper conversion is limited to single-byte characters.
+.Pp 
+.Fn kiconv_add_xlat16_table
+defines a conversion table directly pointed by
+.Ar data
+whose length is
+.Ar datalen ,
+not using
+.Xr iconv 3 .
