C-q is quoted-insert.

The base depends on  read-quoted-char-radix.

225(eight) = 149(ten) = 95(sixteen)

And it works only if unibyte-char-to-multibyte is enabled.
The code used depends on unibyte-char-to-multibyte.
That is, eventually, on nonascii-translation-table or nonascii-insert-offset.
This is set by set-language-environment.

It's probably safest (more universal) to use the ucs input method...

In anycase, once you know what coding system you've configured, you
can easily find the code map on the web, for example on wikipedia.org. 

For example, assuming iso-9959-15, we can see on 
http://en.wikipedia.org/wiki/ISO-8859-15
that the code for € is: a4(hex) =  164(dec) = 204(oct)
so typing

(setf read-quoted-char-radix 10) C-x C-e
C-q 1 6 4 SPC gives:  € 

(set-language-environment 'Russian) C-x C-e
C-q 1 6 4 SPC                                gives:  ╓ 
(set-language-environment 'Latin-1) C-x C-e
C-q 1 6 4 SPC                                gives:  ¤ 


However, 
(set-input-method 'ucs) C-x C-e
u 2 5 5 3                                    gives: ╓
u 0 0 a 4                                    gives: ¤
whatever the language environment.



 
Here is the ISO-8859-15 map:

% ascii -e -d -n

You're always typing.
Well, let's see you ignore my
