How do you make a regular expression to match any number of any single char?
So for example, i match a expression for any single letter or digit. i want to match a double of the first character found.
i.e "ee" in "free"
and "oo" in "loop"
and "mm" in "summer"
using regex.

Depends on where the regex is going, that might work.
