Top Forums UNIX for Advanced & Expert Users Replace hex values using sed command Post 303011207 by RudiC on Monday 15th of January 2018 06:36:35 AM

The line in lalo.txt in post#1 ist a single char followed by a <newline> char. Hex C1 is "extended" ASCII for "Latin capital letter A with acute", which is hex c3 81 in UTF-8.
That's what mayhap garbled your command in post#5 - two bytes for sed's y command.
You need to be very clear about what encoding you use in a) your session, and b) your data files. iconv or recode might do the job for you. Or use octal / hexadecimal representation for sed or tr as drysdalk proposed.

PX_SET_TARGETENCODING(3)				     Library Functions Manual					  PX_SET_TARGETENCODING(3)

NAME
PX_set_targetencoding -- Set encoding for output SYNOPSIS
#include <paradox.h> int PX_set_targetencoding(pxdoc_t *pxdoc, const char *encoding) DESCRIPTION
Sets the target encoding for all alpha fields. It is used when data is retrieved from 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, "targetencoding", encoding) and is deprecated. RETURN VALUE
Returns -2 if recoding is not supported and a value < 0 in case of an error, otherwise 0. SEE ALSO
