Asterisks in text (for matching bold type) #248

I can't find a way to escape a * character in order to match lines containing bold type.

I've tried the following:

$ cat "test_file.md"| mdq \*
Syntax error in select specifier:
┃ *
┃ ↑ unexpected character "*"

and

$ cat "test_file.md"| mdq /\*/
Syntax error in select specifier:
┃ /*/
┃ ↑ unexpected character "/"

and lots of other variations! Indeed the regex /something/ delimiters don't seem to be working at all on my build (installed via cargo/git).
