Fix compile warning when appending UTF-8/ASCII strings to ustring16

Browse Source 
String constants are (const char *), but UTF-8 strings must be treated as
an array of bytes when fiddling with the bits.

The following comparison fails without this change, as uchar8_t is a
signed char, which cannot be 0xC0:

   const uchar8_t* c2 = other;
   ...
   else if (c2[l] == 0xC0 || c2[l] == 0xC1)
   ...
