It's the non-GUI image of Raspbian Jessie. See 
https://www.raspberrypi.org/downloads/raspbian/

I run raspi-config from the command line. The output for locale is as follows:

address@hidden:~ $ locale
LANG=es_US.UTF-8
LANGUAGE=
LC_CTYPE="es_US.UTF-8"
LC_NUMERIC="es_US.UTF-8"
LC_TIME="es_US.UTF-8"
LC_COLLATE="es_US.UTF-8"
LC_MONETARY="es_US.UTF-8"
LC_MESSAGES="es_US.UTF-8"
LC_PAPER="es_US.UTF-8"
LC_NAME="es_US.UTF-8"
LC_ADDRESS="es_US.UTF-8"
LC_TELEPHONE="es_US.UTF-8"
LC_MEASUREMENT="es_US.UTF-8"
LC_IDENTIFICATION="es_US.UTF-8"
LC_ALL=

The only strange thing I see is "LANGUAGE=" which contrast with my non-ARM 
Linux boxes (HP Laptop with Lubuntu, AMD with Debian Jessie LXDE), which show 
"LANGUAGE=es_US:es", but I don't know if it has anything to do with the problem 
because Lynx on Raspberry Pi displays gopher utf-8 correctly for http, but not 
for gopher.

Same thing here. The problem is on Raspberry Pi with Raspbian.

Description: Text-mode WWW Browser with NLS support (development version)
 Lynx is a fully-featured World Wide Web (WWW) client for users running
  cursor-addressable, character-cell display devices.
   It is very fast and easy to use. It will display HTML documents
    containing links to files residing on the local system,
     as well as files residing on remote systems running Gopher, HTTP, FTP,
      WAIS, and NNTP servers.
       .
        This package contains a development version of lynx.

I don't know how important are the differences between Debian and Raspbian, I 
am not familiar with the details. They talk about that here: 
https://wiki.debian.org/RaspberryPi 

I guess my bet will be to follow Thomas Dickey's recommendation on ncursesw. I 
will test that ASAP and will provide you guys with feedback.

Thank you very much for your help.
