unexpected character found in xquery code

Question

I am trying to run the following in my query console.

 xquery version "1.0-ml";

 import module namespace functx = "http://www.functx.com" at "/MarkLogic/functx/functx- 
1.0-nodoc-2007-01.xqy";
 let $forestNames := xdmp:forest-name(xdmp:host-forests(xdmp:host()))
let $databaseForestsIds := xdmp:database-forests(xdmp:database("credits-dh-FINAL"))
return functx:value-intersect($forestNames, $databaseForestsIds ! xdmp:forest-name (.)) 

but i am getting below error :-

 [1.0-ml] XDMP-BADCHAR: (err:XPST0003) Unexpected character found ' ' (0x00a0)

The same code when i run in my colleague's machine it works. where is it going wrong?
