How to prevent Framemaker changing the Link

[Michael Böhme]

Hallo,
I have a Problem which has hopefully an easy solution. I try to make Hyperlinks to open an other PDF on my harddisk. 

I write: 
message openfile "W:\Schadstoffliteratur\Dioxine\Attempt to establish benchmarks for Dioxins.pdf"

Than Framemaker convert this  to: 
message openfile "W:\Schadstoffliteratur‡ioxine\Attempt to establish benchmarks for Dioxins.pdf"

Looking in the MIF I see the following:
<MText `message openfile "W:\\Schadstoffliteratur‡ioxine\\Attempt to establish benchmarks for Dioxins.pdf"'>

The resulting Link does not work, of course. When I repair the link in the MIF manually, open it in FM, print to PDF, it works fine: 
<MText `message openfile "W:\\ElbeSchadstoffliteratur\\Dioxine\\Attempt to establish benchmarks for Dioxins.pdf"'>

But I may not touch the Link in Framemaker again. I want to make hundreds of similar Links, so I am looking for a solution. 

How to prevent Framemaker changing the Link?
