SMS notifications - message character set conversion

Aleksander_Adamowsk2 2007-12-13 20:52:47 UTC #1

Hi!

The next problem I’m facing with SMS notifications is character set conversion.

In order to send an SMS, I need to convert the message text either to
plain ASCII, or to UCS-2. That’s not a problem for me, but the
question is what is the source encoding.

Does current version of eGroupWare always use UTF-8 internally (in my
case for the text of notification that I receive from the
notifications class), or is it configuration dependent? Searching the
current sources didn’t reveal anything conclusive.

How to determine the current eGW text encoding if it’s not always UTF-8?

$GLOBALS[‘egw_info’][‘server’][‘install_charset’] or
$GLOBALS[‘egw’]->translation->charset()

The function also works if no install charset is set (pretty old
installs) and it depends on the language of the user.

Thanks. In my case install_charset was empty, but translation charset was utf-8.

BTW, it’s a pity that these things aren’t documented somewhere…
Google doesn’t find anything for “egw_info install_charset”…

I have one more question which I couldn’t find an answer to in eGW sources.

Given the $preferences variable that holds a user’s preferences object:

$prefs = new preferences($this->recipient->account_id);
$preferences = $prefs->read();

How do I obtain the user’s lang and country? This is needed for
guessing the user’s locale.

I can see in the phpgwapi/inc/class.preferences.inc.php that there’s
come [‘common’][‘lang’] hash, but how do I access it given a
preferences object?

Most of eGW code still uses array, not object oriented access to the
prefs so I couldn’t find an example for this.

Oh, I’ve found ouy using var_export() that this preferences object
holds only data specific to notifications app:

recipient preferences: stdClass::__set_state(array(
‘notification_chain’ => ‘all’,
‘egwpopup_verbosity’ => ‘low’,
‘external_mailclient’ => ‘1’,
))

I need to get to the recipients full preferences, including lang and
country. how to do that?

Hi Aleksander,

it’s system_charset, not install_charset

Hi,

maybe var_export() is not the right command, never used it.

$prefs = new preferences($this->recipient->account_id);
$preferences = $prefs->read();
_debug_array($preferences);

should give your all the prefs of that user. It’s an array of array for
each app.

Hi Aleksander,

it’s system_charset, not install_charset

OK, works, thanks!

Which one is better in the SMS notifications case?
$GLOBALS[‘egw_info’][‘server’][‘system_charset’] or
$GLOBALS[‘egw’]->translation->charset() ?

On my server they both return “utf-8”.

As I said before, the function always returns a result, even with very
old (1.0 and before) eGW installs, for which the charset depend on the
language of the user. For all newer installs (1.2+), the function simply
returns the system_charset.

_debug_array() shows nothing.

Log output:

OK, I’ll go with the function. More backwards compatibility cannot hurt
