Hi

I can read Strings (ASCII-Z) from Modbus registers with HRS as expected. Unfortunately I can’t represent extended ASCII characters (ISO-8859-1) in Labels. I’ve tried to fix it by encoding them in UTF-8 but still no results, nor directly in ISO-8859-1, neither in UTF-8.

An example of the things I’ve tried when converting to UTF-8 could be this:  
ó -\> & oacute; (without the space in between)  
ó -\> 0xC3 0xB3

as stated here [http://www.fileformat.info/info/unicode/char/00F3/index.htm](http://www.fileformat.info/info/unicode/char/00F3/index.htm)

Any hint?

Regards
