I did a major string "spanishification" to a project and got a regression:
I have an #is_integer { text="debe ingresar número" } (ú being the problem trigger)
When that validator gets loaded the connection to the server gets broken.
Meanwhile, In the server I get error:
{[{reason,badarg},
{mfa,{cowboy_simple_bridge_anchor,websocket_info,3}},
{stacktrace,
[{erlang,iolist_to_binary,
[[<<"nitrogen_system_event:">>,
{error,
...
Then dumps js code (I just scope the word "número").
...
cality, { notAnIntegerMessage: \"debe ingresar n">>,
[[[[[[[<<"\372mero\", onlyInteger: true });">>]]]]]]]}]],
[]},
{cowboy_simple_bridge_anchor,massage_reply,3,
[{file,"src/cowboy_bridge_modules/cowboy_simple_bridge_anchor.erl"},
{line,85}]},
Things to consider:
* the #is_integer validator builds the message with this instruction:
Script = wf:f("v.add(Validate.Numericality, { notANumberMessage: \"~ts\", onlyInteger: false });", [Text]),
* the string "número" gets translated by erlang as "n\303\272mero"
Maybe that handling is conflicting with the previous call.
How should I handle this without resorting to ascii only?

Hi Franklin,
You can use a custom validator instead.
#custom {
text="debe ingresar número",
function=fun(_Tag, Value) -> is_integer(Value) end

Hi Franklin,
Are you running from the latest master or is this in a tagged version?
I tried from latest master and did not have problems with the unicode rendering.
If you're running from 2.3.1, give the latest master a shot and see if that helps,

Hi Franklin,
I did some more looking (and wrote a test for this to make sure it works) and I'm finding I'm unable to reproduce this:
Unicode support was fixed in validations on Nov 2014, and the snippet you posted was from a recent version.
Which version of Erlang are you running? I tested with Erlang 18.

Interesting.
Would you be willing to try this:
In a separate directory:
cd NitrogenProject.com
make cowboy run
Then open up http://127.0.0.1:8000/tests_validation
And let me know what happens?
In the Erlang Shell, it should say this:
...Passed (blank_test)
...Passed (fullname_test)
...Passed (allpass_test)
...Passed (passwordconfirm_test)
...Passed (shortpassword_test)
...Passed (badnumber_test)
...Passed (number_out_of_range_test)
...Passed (unicode_value_test)
...Passed (unicode_comparison_test)
...Passed (unicode_comparison_pass_test)
...Passed (unicode_validator_test)
...Passed (clear_validation_test)
...Passed (unicode_integer_test)
Module "/tests/validation" (13 of 13 tests passed)
The last one there (unicode_integer_test) is the applicable one.

Interesting.
The isolated timeouts can /usually/ be ignored.
But the fact that the unicode_integer_test passed is the big thing that's standing out to me indicating that it works in some context with cowboy.
But in your application, there's something there that's causing the conversion from \303\272
From here, there are three ways I can think to debug this, escalating in trust from you:
1) Send me the exact module you're using (either pastebin or email)
or (and this might be a big deal for you)
2) Give me access to the repo and I can try to clone the whole thing (again either github, gitlab, bitbucket or whatever)
or
3) Remote screen sharing to see everything from your perspective.
I know each of these has a level of trust, but this is genuinely confusing me, but without the full context, my initial instincts are failing me.
My email is gu...@sigma-star.com if you want to share that way.
Thanks,
-Jesse

ok, stripped all the code and got this:
-----------------------------------------
-module (establecimiento).
-compile(export_all).
-include_lib("nitrogen_core/include/wf.hrl").
main() ->
#template { file="./site/templates/bare.html" }.
body() ->
wf:wire(submit, textarea, #validate { validators=[
#is_integer { text="ú" } % #is_email fails too
]}),
wf:flush(),
some_text.
-----------------------------------------
the real module was obviously bigger and the path to trigger this
was't throung several postbacks...
As you see, when #is_integer message is nonascii it will raise the
exception: change that to ascii
and all is fine.
it fails with #is_email too and all the wire(...) family functions
fail too (defer, eager)
The point the the "submit" or "textarea" dont exist isn't relevant.

body() ->
wf:wire(submit, textarea, #validate { validators=[
#is_integer { text="ú" } % #is_email fails too
]}),
wf:flush(),
some_text.
-----------------------------------------
the real module was obviously bigger and the path to trigger this
was't throung several postbacks...
As you see, when #is_integer message is nonascii it will raise the
exception: change that to ascii
and all is fine.
it fails with #is_email too and all the wire(...) family functions
fail too (defer, eager)
The point the the "submit" or "textarea" dont exist isn't relevant.

So this module works fine when I copy it into my projects.
It properly generates this:
Nitrogen.$anchor('page', '.wfid_textarea');v.add(Validate.Numericality, { notAnIntegerMessage: "ú", onlyInteger: true });
Would you be willing/able to zip up the whole project (stripped of anything you don't feel comfortable sharing) and share it with me? (Are you running linux, btw?)
Seeing this happening in context will help to figure out what's going on here.

Weird, the development repo is from 2 months ago.
Yesterday, I cloned the test repo you told me, I put that module (establecimiento.erl)
and It also dies with error.
Here is the package (it is the repo you told me to clone yeasterday) with the synthetized
module
https://drive.google.com/open?id=0BzZ8yE1UITBdQ1VldE9PQ1BvTGM
the error traces here: https://drive.google.com/open?id=0BzZ8yE1UITBdUFJYdU4xQ2tGLWM
I access http://localhost:8123/establecimiento , and KABUUM?
I'm on slackware, in the office and in the home (different computers).
I tried setting LANG=C, no changes.

Thanks.
I had to wipe full release's libraries due to dependent libraries not working (something with ssl), so I wasn't able to completely reproduce your environment. And once I got the system to load, it worked as expected.
BUT...
I suspect there's something up with your Erlang installation, particularly the unicode library. From your stacktrace, the existence of the {error, X, Y} tuple in the value attempting to be converted to binary by cowboy (see attachment) indicates that the unicode:characters_to_binary/1 call is crashing at the ú character in your system.
If you run the following from the erlang shell, what do you get?
unicode:characters_to_binary("ú")
I want to request that you actually *type* the command rather than copy-and-pasting it.

Interesting.
This is quite the perplexing error.
It's been a while since I've compiled Erlang from source, but is Erlang compiled from source, or did you use a version from a package manager? For folks running Debian or Ubuntu, I typically recommend installing the packages from erlang-solutions.com, but on Slackware, I'm assuming you've installed from source.
But I'm sort of at a loss here. I had a look through the compile switches, but I didn't see anything that particularly stood out that would cause unicode handling to fail.
You could try using binaries instead of strings and see if that helps.
Like
<<"ú"/utf8>>.
And see if it handles it better.
But I'm just spitballing here,
