Webdialog to ruby encoding issue on OSX

jiminy-billy-bob

This is the one, thanks guys!

John, your solution works well when sending the string back to the webdialog. But in my case I'm trying to read the string inside ruby (actually change layers names).
The problem is that ruby reads the unicode as is, without converting to actual characters. I end up with layers called something like "\u00E9" in SU's layer window (But it displays fine in my webdialog)

I can't find a solution on google. Do you guys have any idea what I should do?

Is it execute_script being the issue? (Sorry, loooong thread - got confused.)

are you single quoting it?

> "\u00E9"
é
> '\u00E9'
\u00E9
> %q(\u00E9)
\u00E9
> %Q(\u00E9)
é

or maybe use .inspect?

"\u00E9".inspect
"é"

post a snippet, and I'll run some checks...

I did write a ruby encode/decode, but didn't need it for what I was doing...

I'll see if I kept it

Is your HTML in UTF-8 and tagged with a UTF-8 meta tag so the HTML engine knows to use UTF8?
I tried that ç character in SKUI and it renders fine:

I'm not doing anything special, other than ensuring the my RB files are UTF-8 encoded, that my HTML files are UTF-8 encoded (with UTF-8 characterset META tag.)

Ditto on OSX:

I think we need a full example of the error you get - packaged up as RBZ.

Btw, what is the source for this character?

@TT

the third last post from the other thread has a rbz that shows the issue on a mac...
http://sketchucation.com/forums/viewtopic.php?f=180%26amp;t=57074%26amp;start=30#p518959

returns using 'get_element_value' have bad encoding regardless of html declarations, script encodings, etc...

something is happening internally in SU that screws things up...

try the rbz it's harmless...

I was going to but I got distracted by work and it's still on my endless todo list...

So this only happen on OSX, not on Windows?

as far as I'm aware it's a mac thing...

I think it's because the internal bash env locale defaults to "C" if not implicedly set

> %x(locale)
LANG=
LC_COLLATE="C"
LC_CTYPE="C"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

whereas same call in 'Terminal.app'

LANG="en_US"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

because it is set...

Going back to your test here

If you add

Sketchup.active_model.layers.add param_fix

in @dlg2.add_action_callback("trans_L8_fix")

The layer name is displayed "élan 勢い Schwung импульс" in Layers Panel, as it is a webdialog.
But in Sketchup's layer window, it's displayed "\u00E9lan \u52E2\u3044 Schwung \u0438\u043C\u043F\u0443\u043B\u044C\u0441", just like what's printed in the ruby console.

Any thought on that?

I think this is because SU does not set ENV["LANG"] when launching the subshell.

@ Steve
do you think the two are unrelated?

@jiminy-billy-bob said:

if I eval it double quoted, I get élan 勢い Schwung импульс

    puts (eval('"' + param_fix + '"'))

works in UI.messagebox that way as well.

alternatively I wrote [so it is possible] a simple decode method by reversing the JS function back in ruby, it worked but i can't find it...

eval works great, thanks!

It's possible they have the same cause, but I am not sure how to prove that.

The man page for the locale command says:

 LANG         Used as a substitute for any unset LC_* variable.  If LANG is unset, it will
              act as if set to "C".  If any of LANG or LC_* are set to invalid values, locale
              acts as if they are all unset.

So the behavior you get is consistent with LANG not being set by SU when it launches a subshell. Also, if you set ENV[LANG] to a specific locale such as "en_US.UTF-8" in the Ruby Console before doing the %x, the other variables all follow.

So far as I can tell, SU doesn't launch a separate process for a WebDialog (at least I don't see one reported in Activity Monitor). I don't know what environment a WebDialog gets...can it be read from javascript?

hi TT

did you get a chance to run this on your mac?

and did it confirm what I state, on your setup?
