* the byte is not printable.
* So, for example, the extension value consisting of the following
* bytes:
* 0x30,0x14,0x31,0x12,0x30,0x10,0x06,0x03,0x55,0x04,0x03,
* 0x13,0x09,0x4a,0x75,0x61,0x6e,0x20,0x4c,0x61,0x6e,0x67
* is output as:
* 30 14 31 12 30 10 06 03 0.1.0...
* 55 04 03 13 09 4a 75 61 U....Jua
* 6e 20 4c 61 6e 67 n Lang
* The allocation size therefore requires:
* - 4 characters per character in an 8-byte line
* (2 for the hex format, one for the space, one for the ASCII value)
* - 3 more characters per 8-byte line (two spaces and a newline)
* - 1 character for the terminating nul
* FIXME: should use a fixed-width font for this
