Re: [RFI] octstr_recode

Re: [RFI] octstr_recodeIf the message is really not iso-8859-1, yes, we have to process the ucs2 (or utf8) externally.

But iso-8859-1 is differente from gsm_alphabet.

My ericsson T68 sends the message in unicode if I insert one accenter char.

Imagine that I have a service with a keywork test

If I send "test hello ããã hello", ericsson sends in unicode and kannel couldn't understand that
it's the test service and the "hello ããã hello" text.

With my patch, kannel understands and it works smoothly...

    I'm trying to use the octstr_recode function to convert a MO message from UCS2 to
    ISO-8859-1 or UTF-8

    I was thinking in trying to recode to ISO-8859-1 if possible, otherwise convert to UTF-8
    and set coding acordly.

    I thought that if the text couldn't be translated to ISO-8859,
    octstr_recode (octstr_imm("iso-8859-1"), octstr_imm("UTF-16BE"), text)) would
    return false and I could switch to
    octstr_recode (octstr_imm("utf-8"), octstr_imm("UTF-16BE"), text)

    but the first recode converts my %06%4A to a ي and returns ok.

    May I search for &#xxxx; in utf16-be to iso8859-1 and reject it, switching then to utf8 ??


  I understand your goal. Support incoming Unicode.
  Well the question is do we need to recode in this case?
  If the incoming message is in unicode, its most probably not readable by us (being iso8859-1 only humans)). So why not simply carry them along "as is". the coding in DCS from the incoming message tells us its unicode, and thats enough for us.


  The only thing I see a problem with is SMSbox'es keywords where it would have to split off a keyword (ok that can be done) but then we need to enter non english keywords in a ascii textfile which gets tough....
