The # character is a URL metacharacter - it means something specific within
the context of a URL. If you want to use a metacharacter as a literal
character, you need to escape the metacharacter. If you're building a CF
page, this is easy to do with the URLEncodedFormat function:
<cfoutput>
<a href="#URLEncodedFormat("/documents/interview with john smith
#1.doc")#">Download file a</a>
</cfoutput>
If you're not building a CF page, you will need to manually escape the
characters with their matching escape sequences. The URL encoding sequence
for "#" is "%23":

For that matter, spaces are invalid characters within a URL as well,
although most modern browsers will automatically escape them.
