John might have been referring to the large swathes of Unicode that don't necessarily have an 'obvious' representation in such a form. For example: * CJK-related characters; * the "Musical symbols" characters; * many of the "Miscellaneous symbols" characters. Additionally, there are lots of opportunities for bikeshedding over the representations of certain characters. Take ☺, WHITE SMILING FACE. Off the top of my head, i can imagine that being represented by ':-)', but i frequently encounter people using ':)' and '(-:' to represent the 'smiling face' concept instead. Together, these issues seem to me to suggest that it might be non-trivial to attempt to build a table of ASCII representations of various Unicode characters. Alexis.
