Saving (unusual) linux filenames

[AmFreak at web.de]

Hi,

i have a script that reads and writes linux paths in a file. I save the  
path (as unicode) with 2 other variables. I save them seperated by "," and  
the "packets" by newlines. So my file looks like this:
path1, var1A, var1B
path2, var2A, var2B
path3, var3A, var3B
....

this works for "normal" paths but as soon as i have a path that does  
include a "," it breaks. The problem now is that (afaik) linux allows  
every char (aside from "/" and null) to be used in filenames. The only  
solution i can think of is using null as a seperator, but there have to a  
cleaner version ?

Thanks for any help
