It turns out there is an append() function for characters, that looks like this: C strings that you should use in small memory environments are char arrays where the text is ASCII coded characters ending in a terminating 0 (ASCII NULL) Please avoid C++ String objects with Arduino. This function assigns a particular character to a string's end. A valid C string requires the presence of a terminating "null character" (a character with ASCII value 0, usually represented by the character literal '\0')..
