replace function with ascii

Hello,
I cant seem to find documentation on this type of error. The trouble I am having is replacing an ascii character with something else.

For example,
<cfset some_text="foo & bar">
<cfoutput>#replace(some_text, "&", "+", "All")#</cfoutput>

Outputs
foo & bar

And not the desired
foo + bar

Removing the quotes around & gives a missing argument error:

"When using named parameters to a function, every parameter must have a name."

I use the ampersand as an example, I know that I could simply type the ampersand in, but the actual char I am using in my code is &#149, which isn't on the keyboard.

Thanks in advance

Not sure if there is a way to do it with ascii codes, but what about character codes?

#replace(some_text, chr( 38 ), "+", "All")#

You can see the whole list at

Thanks, that works fine. I had some trouble finding the chr value for &#149, but with the help of a more seasoned programmer he found it to be chr(8226) using a cfloop and char. Go figure. Thanks again for your much needed direction!

<cfset some_text="foo & bar">
<cfoutput>#replace(some_text, "&", "+", "All")#</cfoutput>

^^ As far as I know, the reason that wasn't working was because the & isn't processed at server side, and the replace function was looking for an unprocessed (literal) "&" string. Would have worked if used:

<cfset some_text="foo & bar">

Kiteless provided the solution, I thought I might explain the failure ;P
