p The .Fn kiconv_add_xlat16_cspair function defines a conversion table using .Xr iconv 3 between .Fa fromcode charset and .Fa tocode charset. You can specify .Fa flag to determine if .Xr tolower 3 / .Xr toupper 3 conversion is included in the table. The .Fa flag has following values.

p l -tag -width ".Dv KICONV_FROM_LOWER" -compact t Dv KICONV_LOWER t Dv KICONV_FROM_LOWER It generates a tolower table in addition to a character conversion table. The difference between two is tolower .Fa tocode or tolower .Fa fromcode . t Dv KICONV_UPPER t Dv KICONV_FROM_UPPER It generates a toupper table in addition to a character conversion table. The difference between two is toupper .Fa tocode or toupper .Fa fromcode . .El

p A tolower/toupper conversion is limited to single-byte characters.

p The .Fn kiconv_add_xlat16_cspairs function defines two conversion tables which are from .Fa localcode to .Fa foreigncode and from .Fa foreigncode to .Fa localcode . These conversion tables also contain both tolower and toupper tables.

p The .Fn kiconv_add_xlat16_table function defines a conversion table directly pointed by .Fa data whose length is .Fa datalen , not using .Xr iconv 3 . .Sh SEE ALSO .Xr iconv 3 , .Xr tolower 3 , .Xr toupper 3
