Re: [PATCH 1/4] Add so called reduced charset support to SMS

This "reduced" charset support is available in some current phones to reduce the number of segments that a message takes. Normally, when characters are encountered that don't have a representation in the GSM 7 bit alphabet, the encoding switches to UCS-2 that takes roughly twice as much space. This reduced charset feature transliterates the input string, so that more unicode characters fit the GSM alphabet. The obvious downside is that transliterating loses information, i.e., the text gets dumbed down, and what the recipient receives is not the original text. Nevertheless, in some regions, this is a must-have feature. --- src/util.c | 137 +++++++++++++++++++++++++++++++++++++++++++++++++++--- src/util.h | 4 ++ unit/test-util.c | 18 +++++++
