Generates a code set conversion table for use by the lconv library.
genxlt [OutputFile ]
The genxlt command reads a source code set conversion table file from standard input and writes the compiled version to the file specified by the OutputFile parameter. If a value is not specified for the OutputFile parameter, standard output is used. The source code set conversion table file contains directives that are acted upon by the genxlt command to produce the compiled version.
The format of a code set conversion table source file is:
%token <blank> # <tab> and <space> %token <hex> # <zero>, <one>, <two>, <three>, <four>, # <five>, <six>, <seven>, <eight>, <nine>, # <a>, <b>, <c>, <d>, <e>, <f>, # <A>, <B>, <C>, <D>, <E>, <F>, %token <any> # any character but '\n' line : offset blank value blank comment '\n' | 'SUB' blank value blank comment '\n' ;
A line where the offset is 'SUB' is used to specify the default substitution character.
If the table is set to 'substitution' , the iconv converter using this table uses the SUB value for this offset.
If the value is set to 'invalid' , the iconv converter using this table returns error for its offset.
If the offset is found in the source code set conversion table file multiple times, the last entry is used in the compilation of the translation table.
The offset and value must be in the range of 0x00 through 0xff, inclusive.
The following is an excerpt of a code set conversion table:
SUB 0x1a substitute character
0x80 0xc7 C cedilla
0x81 0xfc u diaeresis
0x82 0xe9 e acute
0x83 0xe2 a circumflex
0x84 0xe4 a diaeresis
0x85 0x40 a grave
If successful, the genxlt command exits with a value of 0. If the output file cannot be opened, the genxlt command is unsuccessful and exits with a value of 1. If a syntax error is detected in the input stream, the genxlt command will exit immediately with a value of 2, and write to standard error the line numbers where the syntax error occurred.
The name of the file generated by the genxlt command must follow the naming convention below in order for the iconv subsystem to recognize it as a conversion file:
fromcode: "IBM-850" tocode: "ISO8859-1" conversion table file: "IBM-850_ISO8859-1"
The conversion table file name is formed by concatenating the tocode file name onto the fromcode file name, with an underscore between the two.
To generate a non-English, user-defined code set conversion table, enter:
cp /usr/lib/nls/loc/iconvTable/ISO8859-1_IBM-850_src $HOME vi $HOME/ISO8859-1_IBM-850_src genxlt < $HOME/ISO8859-1_IBM-850_src > cs1_cs2
The iconv command.
The iconv_open subroutine, iconv subroutine, and iconv_close subroutine provide a method to use the conversion service from within a program.
