Set the encoding for data retrieved from a character field. All character fields will be recoded to the encoding set by this function. If the encoding is not set, the character data will be returned in the DOS code page encoding as specified in the database file. The encoding can be any string identifier known to iconv or recode.
This function is deprecated and should be replaced by calling px_set_parameter().
See also px_get_info() to determine the DOS code page as stored in the database file.
