This should show non-printable characters in vi.
Actually, with most versions of unix, ":set list" only affects white space. It causes tabs to show up as ^I and newlines to be marked with $.

The real problem is that some bytes could have values in the range of 128 to 255 and you may not have an 8 bit data path to your terminal. Depending on the stty settings, the MSB may be a parity bit rather than a data bit. Also not all terminals will display something for non-ascii characters. And a final problem is that, I think, vi balks at attempting to display nulls, although it will count them and display a count at startup time.

The bit order of the font should be requested as MSBFirst (most significant bit first). The byte order of the font should be requested as LSBFirst (least significant byte first). The byte order of the font should be requested as MSBFirst (most significant byte first). Only the character extents should be displayed, but not the bitmaps. The start of the range of the characters to display (char is a number). The end of the range of the characters to display (char is a number). The scanline unit of the font (8, 16, 32, or 64). The scanpad unit of the font (8, 16, 32, or 64). The bitmap padding unit of the font (0, 1, or 2, where 0 is ImageRectMin, 1 is ImageRect- MaxWidth and 2 is ImageRectMax). Do not show the font properties. DESCRIPTION
The showfont command displays data about a font that matches the given pattern. The information shown includes font information, font prop- erties, character metrics, and character bitmaps. The wildcard character "*" can be used to match any sequence of characters (including none) in the font name, and "?" can be used to match any single character. The "*" and "?" characters must be quoted to prevent them from being expanded by the shell. If no pattern is given, "*" is assumed. ENVIRONMENT
