Replacing Trademark Character

[c_pattle]

I have a php script that needs to replace trademark symbols in a string. At the moment it works by doing

 

str_replace(™, '', $string);

 

This works when I have tested it on Windows but is this a bad way of doing it? I'm guessing it is. Does anyone know a better way.

 

I know I could convert the string to html entities and then replace the html code but I don't want to do this as there are other things in the string I don't want to convert to html entities.

 

Thanks

That works just fine, as long as you ensure that the search string and the haystack are encoded with the same charset. Which they have to be, seeing as it works.

 

PS: Just remember to quote the TM symbol, as it's not a constant.
