MC35i modem and special characters

One of the features of this modem is that it cannot send some special characters (e.g. °). So if an alarm SMS is defined in RcWare Vision or in the Touch screen editor for an analogue that measures, for example, temperature and has degrees Celsius as units, then it simply will not be sent with this modem. On the other hand, Siemens MC75 or Wavecom can send it.
