key combinations (Euro symbol and others)

Hi, i'm Angelo.
Sorry for my bad EN
Pidgin 2.7.0 on Winzozz XP SP3
but the problem is old...(for me) by system version and by pidgin version: 
i've start with 2.5.4 on Xp without sp...
I've read the support archive but without find solutions (I hope I've searched 
well, or are not able to find it)
I use pidgin for job more than for play, and often i need write other 
characters over the alfabetical ones
the prob: how i can use the key combination on my keyboard to input in one 
string the desired character? often i need to use the Euro symbol € or the 
symbol @,  the Diesis symbol # and the square brackets [ ]
So far, i've copied and pasted from the block note every time i've needed to 
write one of this.
There is other way to input this symbols in my dscussions or i must continue 
with this workaround?
thanks for the time spent on read this mex
