Yes you are right. I did a bit-shifting error in my mask and don't see it during my test. It's 0xc and not 0x6 to use for the mask. The issue that I've is effectively due to the fact that some SIMs use the '1111' Coding Bits Entry (it's the case for French Orange SIM card for example). For me having the upper bits set to '1' do not really changes the character set decoding (only diff is that UCS2 will not be possible in that case). It's the reason why I've simply add a mask in the decode_text function. Using the sms_dcs_decode function is probably better as the DCS of the SIM ToolKit is the same as the one used for SMS. Do you want that I re-publish a patch using the sms_dcs_decode function?
