If you open the file (temperatura.txt) with nano, you can see the spaces.
Thanks Smilie

I'll keep trying Smilie
Hi, if you look at the description of your attachment in your post it says 3 bytes. That is a 6, a 4 and a newline character. So there are no spaces there, that is just nano.
Code:
$ od -c temperatura.txt
0000000   6   4  \n
0000003

NAME
iconv -- codeset conversion utility SYNOPSIS
iconv [-cs] -f from_name -t to_name [file ...] iconv -f from_name [-cs] [-t to_name] [file ...] iconv -t to_name [-cs] [-f from_name] [file ...] iconv -l DESCRIPTION
The iconv utility converts the codeset of file (or from standard input if no file is specified) from codeset from_name to codeset to_name and outputs the converted text on standard output. The following options are available: -c Prevent output of any invalid characters. By default, iconv outputs an ``invalid character'' specified by the to_name codeset when it encounters a character which is valid in the from_name codeset but does not have a corresponding character in the to_name codeset. -f Specifies the source codeset name as from_name. -l Lists available codeset names. Note that not all combinations of from_name and to_name are valid. -s Silent. By default, iconv outputs the number of ``invalid characters'' to standard error if they exist. This option prevents this be- haviour. -t Specifies the destination codeset name as to_name. EXIT STATUS
The iconv utility exits 0 on success, and >0 if an error occurs. SEE ALSO
iconv(3) STANDARDS
iconv conform to IEEE Std 1003.1-2001 (``POSIX.1''). HISTORY
