***** = *** in gchat why?

i am just shooting a question asked by my friend. if you give continously 5 stars in chat menu of your gmail account, it just displays 3 stars. why is that?

It is not specific for just five stars.
If you enter any no. of stars greater than 2 they will reduced by 2.
But it is neither a bug nor an easter egg.
From my observation what i found is that if you place any text between 2 stars then it is converted to bold
e.g.
*hi*
will look like
hi
so,
*****
looks like
***

thank you so much.. ! :)
