See Encode, as well as perlunitut and perluniintro.

But the data shown doesn't seem to be unicode. If it was, this 

DepM-ssito Centralizado

would instead be

DepM-CM-3sito Centralizado

So, the data is some ISO-8859 variant. In ISO-8859 the ó is chr(243), which is chr(ord ('s') | 128) (hence the output as M-s) and the character with the high bit set in

London andM-  NewYork

is most likely chr(160), i.e. a non-breaking space - chr(ord (' ') | 128).

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
