How to make IE read "tildes"

I think this is a random question :stuck_out_tongue: Anyway…

I´m having troubles with IE (who doesn´t) I have to launch some pdf files which url have “tildes”: á, é, í, ó…for example: manualdegestión.pdf, with Firefox no problems at all, with IE it doesn´t work, and I NEED them to be with “tilde”. What can be done in this case? I checked the options but didn´t see anything… thanks!
