SMS support a very own 7-bit character set (GSM 0338), which contains some UTF-8 characters such as e.g. German umlauts, but not e.g. ó or Chinese, Arabic, Cyrillic characters, etc. For this, a unicode SMS would have to be sent, which is coded with 8 bits and therefore requires only 70 characters space per SMS. A Unicode SMS with e.g. 120 characters would hence cost twice as a normal SMS.
Here you can learn more about the specifications of the SMS character set and see the complete list of allowed characters in normal (not unicode) SMS: https://en.wikipedia.org/wiki/GSM_03.38#GSM_7-bit_default_alphabet_and_extension_table_of_3GPP_TS_23.038_.2F_GSM_03.38.
