They had 9 bit chars. They had any size chars you wanted from 1 to 36, but some char sizes produced a lot of internal fragmentation. The most efficient sizes were 1 (36/word), 2 (18/word), 3 (12/word), 4 ( 9/word), 5 ( 7/word + 1 bit), 6 ( 6/word), 7 ( 5/word + 1 bit), 8 ( 4/word + 4 bits), 12 ( 3/word), and 18 ( 2/word), Nine-bit characters were an especially wasteful size, as you could only get three per word. Might as well use 12-bit chars. The "7-bit char plus 1 bit to indicate a line number" was probably the most common, although the 6BIT representation was used a lot in the systems code...
