This sounds like an encoding Problem of your email. 
The "Ó" in your filename is not presentable with 7bits, so it needs to be 
encoded in some other way. Unfortunally RFC1806 says:

2.3
[...]
Current [RFC 1521] grammar restricts parameter values (and hence
Content-Disposition filenames) to US-ASCII.  We recognize the great
desirability of allowing arbitrary character sets in filenames, but
it is beyond the scope of this document to define the necessary
mechanisms.  We expect that the basic [RFC 1521] `value'
specification will someday be amended to allow use of non-US-ASCII
characters, at which time the same mechanism should be used in the
Content-Disposition filename parameter.

So I would say you can only rely on the correct interpretation of your 
attachements when using only 7Bit ascii filenames. I know many clients 
support other that[0], but as far as there is not standard for this you will 
get problems. 

Which client are you using for sending the mail? 

[0] AFAIK Kmail for example uses url-encoded filenames for this on sending. 
This must be understood by the other site.
