This is a maybe a trivial question, but I have not found the explanation in
help (I am using Mathematica 7.0.0):
Normally a string matches itself:
In[270]:= StringMatchQ["monkey", "monkey"]
Out[270]= True
But
In[271]:= StringMatchQ["\\*", "\\*"]
Out[271]= False
Why? Compare also to
In[4]:= StringCases["\\*", "\\*"]
Out[4]= {"\\*"}
In[267]:= StringPosition["\\*", "\\*"]
Out[267]= {{1, 2}}
