SYNOPSIS
#include <paradox.h>
int PX_set_inputencoding(pxdoc_t *pxdoc, const char *encoding)
DESCRIPTION
Sets the input encoding for all alpha fields. It is used when 
data is stored into a record. The encoding must 
be a name as it is described by the man and info pages of 
recode or iconv                         whatever is used. A common value is `latin1' on Unix 
systems. If you do not set the encoding the function PX_get_data_alpha(3) 
will return field data in the original encoding otherwise it will 
recode the field data. 
This function is a short cut form PX_set_parameter(pxdoc, "inputencoding", encoding) and is deprecated.
RETURN VALUE
Returns -2 if recoding is not supported and a value < 0 in case of an error, otherwise 0.
