Hi,

Goal: Replace multiple characters in a text string. I want to replace all occurences.
Parser: Altova built-in parser
OS: Windows XP
Issue: First character in the search replaces all occurences
  Second character replaces last character, not first occurence
Third character does not get replaced

Source XML
<root>
<content>Register symbol® Copyright symbol© registration symbol again® trademark symbol™ copyright symbol again©</content>
</root>

Output XML (ignore "_" underscore in numeric character entities)
<root>
 <content>Register symbol&_#174; Copyright symbol© registration symbol again#_174; trademark symbol™ copyright symbol#_169; again</content>
</root>
