No alternation, no /e, just soft and pink.

s/(?!\d[.,]\d)(.[^\w\s])(?!\s)/$1 /g;

Update
Just noticed how similar this is to ysth's solution, but his use of lookahead/lookbehind is really advanced.
...and...
Had removed the dot from the group. Need that. (Thanks, dda.)

Hmm.. Just tried:

$_ = "1.2.a.b";
s/(?!\d[.,]\d)([^\w\s])(?!\s)/$1 /g;
print;

Prints "1. 2. a. b"
