Declaration

define external string sink function euc-output-file
                value string filename
  exceptions-to value io-exception exceptions-to optional

This function accepts UTF-8 encoded data and writes that data to the file named in the "filename" argument, converting the UTF-8 encoding to EUC encoding. The program writes out UTF-8, but the file receives EUC.

Arguments:

• "filename". The name of the EUC encoded file you want to write. If a zero-length "filename" is used (that is, ""), then euc-output-file does not open a file, but writes to standard output. The zero-length "filename" option allows the conversion functionality to be used in an OmniMark program that is being used as a filter.
• "exceptions-to". This optional argument indicates that errors are to be recorded in the passed "io-exception" object, and that the OmniMark program is not to be immediately terminated. There are three types of errors, categorized according to how they are handled:
  • Whenever an invalid or out-of-range encoding is found, it is converted to the ASCII DEL character (0x7F) on output. If "exceptions-to" is specified, the "io-exception" object is marked for a data encoding error, and the function continues processing.
  • If the external string sink function cannot be created, either because the declaration does not match what is expected or because there is not enough memory to create the output object, an error is signaled to OmniMark, and your program is terminated.
  • If "exceptions-to" is specified, then for any other type of error that occurs during memory allocation, file opening or closing, or reading or writing, the "io-exception" object is marked for the error found, and processing continues. If "exceptions-to" is not specified, an error is signaled to OmniMark and your program is terminated.

The file format is interpreted according to the Japanese Industry Standards JIS X 0201, JIS X 0208, and JIS X 0212, with the addition of EUC encoding of the single bytes and of the byte pairs. No escape sequences are used by EUC.

Example:

  ; Setting a file containing EUC-encoded Japanese text, to the contents of a
  ; local buffer.
  
  set euc-output-file "myfile.euc" to my-buffer
