Hi,
Sorry for budding in. I don't know what you mean by exactly correct
solution, but in Greece we have been using an approach like Mike's for all
this time. A GSM 7 alphabet, can only pass 127 values. You have to give
support to all Latin 1 caps + printable symbols, which leaves 55 places for
other GSM specific chars (lower case + non-printing). Of those 10 are used
by the Greek special characters. Incidentally Delta corresponds either to
linefeed or DLE (Data Link Escape), both not printing in the ascii table.
So, whatever you do, assuming that all other 55 places are covered by
special GSM symbols, only 10 of those are lost. But then again there is a
limit to the places you can use in a 7bit alphabet.
BR,
Nikos

hello Mike,
thank you for your answer!
i am suspecting that you leave the smpp connection to it's default charset
(that is gsm7), right?
this way, yes, greeks will do pass correctly however that does not stand for
many other gsm7 character, right?
yes, in most cases you won't need them but was looking for a completely
"correct" solution.
it seems, after reading Thanos' patch, that such solution is not possible
unless you patch kannel like Thanos suggested (was trying to avoid this).

talk about synchronicity!
I just faced (and solved) the exact same issue.
here is what to do :
1. make sure that your message is encoded in WINDOWS-1253
2. change all greek letters to upper case, no accent
3. search the message, and replace ALL characters EXCEPT the 10 Greek
characters, to their English equivalents
so, Greek alpha 0xC1 becomes 0x41, BUT greek DELTA stays as it is !
4. url-encode the text of the message
5. add the following parameter to your HTTP GET API call :
charset=WINDOWS-1253
(so that Kannel understands the 10 greek characters)
done !
this worked for me, (30 minutes ago) just fine, for vodafone SMSC. it may
work for the other providers as well, who knows...
PS this procedure may also work if the message is encoded otherwise, e.g
unicode, but I have not tested it. the main idea to keep is that you REPLACE
all greek charcters EXCEPT the 10...

Subject: smpp latin1 and greek chars....
hello everyone,
i have an smpp connection with alt-charset parameter set to latin1.
the provider mapped the (missing from latin1) 10 capital greek letters
included in the gsm charset into their exact same position in the latin1.
meaning that for instance the greek capital letter Delta (Δ) is mapped on
latin1 position 0x10 (which happens to be the exact same position in gsm
charset).
my problem is that i can't convince kannel 1.4.3 using it's http api to send
any of those characters. it converts them to "?" no matter what i do.
any ideas?
kind regards,
