to which Luca Saiu <luca@ageinghacker.net> replied:

The fact that the delimiters “*” and “_” are symmetrical makes it
difficult to parse them and introduces the possibility of mismatches.
How would we render “*a*b*c*d”? And “*a*b*c*d*”?

I would agree that single character '*' and '_' delimiters aren't going

to work well.

Better, but maybe not perfect, would be regular expressions matching

"\w\*[a-zA-Z0-9-]+\*[.,;!]?\w"and "\w_[a-zA-Z0-9-]+_[.,;!]?\w", where

"\w" means word separator / whitespace ([ \t\n\r] etc.).

So, then,

"*SURPRISE*!!" would match (assuming word separation),

"*a*b*c*d*" would (with word separation) unambiguously be <em>a*b*c*d</em>,

"*a*b*c*d" would not match (be rendered as written), and

"Please be _very_ careful." would contain <u>very</u>.

I would think that good regular expression matching would be able to

separate the common cases from the unusual or potentially ambiguous

ones.
