Are all characters in a string stored with the same "width"? IOW, does the presense of one Unicode character in the range U+010000..U+10FFFF in a string that is otherwise all 7-bit ASCII values result in the entire string being stored 4-bytes per character? Or is the storage width variable within a single string? -- Grant -- https://mail.python.org/mailman/listinfo/python-list
