Some languages have characters that are not included in the GSM Character Set. For example some languages that include non GSM characters include: Greek (Θ θ, Ι ι, κ, Λ, λ) and Polish (ń, ś, ż).
However if you set your SMS content to include non GSM characters and it is sent through this method, because the characters that are not in the default GSM char table, the message received by the recipient will contain errors.
Qudini does have Unicode encoding for SMS characters:
Unicode encoding is used to send any character that is not in the default GSM char table. (eg. Greek, Korean or Arabic etc). You'll need to contact email@example.com and let us know if you wish to do so.
However there is a trade off: the character limit for Unicode encoded messages is reduced from 160 to 70 characters. SMS can still be set to more characters than this limit, however if the message content is longer than the limit it will counted as another SMS will increase the number of messages used each month.
If you do need to send non GSM character SMS in a Unicode encoded method, we recommend shortening your SMS to be as concise as possible ensure it can only be 70 characters, and then utilise the weblink feature which has no character or language limitations. A Qudini support representative will be able to support you to change this for you.
