The first time I needed such a code for KWord's AbiWord export filter, I took 
it from KWord's ASCII import filter if I recall well. I have never thought 
about its cost.

But such code do exist in many of KWord's filters:
- ASCII (Import)
- AbiWord (Export)
- Applixword (Import)
- DocBook (Export)
- HTML (Export)
- RTF (Export)

So if there is anybody volunteers to create such a function, it would be very 
usefull. The maximum are 5 expressions (for AbiWord: &amp; &lt; &gt; &quot; 
&apos; )

The Latex export filter seems to use QString::replace too (in textzone.cc) 
but the use seems to be more complicate than for the filters listed above.
