Hi, I'd need more specific information to answer your question. The standard is that when GSM text messages are sent out over the air, a 7-bit character set is used which allows 160 characters to be packed into a 140 byte message. This process is referred to as GSM 7-bit packing. However, 7-bit packing is normally only used when sending via a GSM modem (or when a message includes special attributes) ... as most SMSC interfaces use an 8-bit (normal text) interface. So I'd need more clarification of what context you are asking about enabling GSM 8-bit ... if it is for a specific SMSC type, or ??? DCS=28, assuming that the 28 is a hex value would indicate Unicode (UCS2/16-bit) encoding. Normally DCS=8 would be used for Unicode. DCS=28 indicates Unicode with GSM compression, which my understanding is that no major handset vendors have actually implemented the compression algorithm. Maybe you are talking about 16-bit/Unicode messaging? NowSMS natively supports Unicode, defaulting to using the UTF-8 character set for text input. If a text message cannot be represented using the GSM 7-bit character set, NowSMS automatically uses 16-bit Unicode/UCS2 instead. -bn |
