+ The -f l1 option tells iconv to convert your
+ Latin-1 file, supplied in argument $2, while
+ the "-t utf-8" options tell iconv to return a UTF-8 encoded file.
+ The result is redirected into argument $3.
+ The echo "{-# LINE 1 \"$2\" #-}"
+ just makes sure that your error positions are reported as
+ in the original source file.
