Description of the problem:
Hi!

I am now looking at the data of my experiments. While some look fine and show all the information that I want to, some have a very different format and are in different signs. It looks like this:
“mÀ·gvÏzc`dI,U–R™ÚÌT©ÝÆø·oÌK<—7˜jïvc°»¤Šçdä‰8oÜ#òĤµ©»?ÖäYù³ßüêÛ_ýìۗ}ó‹Åöåp»xÞîßÿ<O‹¤ô—f™ËgoMêF¿ºyç’Úä9÷³ßþ¯ÿñ³_ïšå¡¹_¼6ë»íSó×æ»çõr³<¬¶›¿šï‹÷‹oýþtX=ý|±Y>5﹔·‹×ÕæýŸW›ûíë1iÿÃíâãËz½¿Û½?ì^šÛÅÝv½Ý½ÿo»?·‹ÜÜ.–/‡íovË×÷eŸ²ÿñ›íÃ1ýËfuØ¿ÿÔ¬>¿ò_ÒÛô?}²ÍÝ’oé®ÙšÝíb¿ú¾yÿ²¹o>®6Íýíb»[ímŸ—w«ÃßÞg·‹ûæùðéøë»õêùËýãñÇ[¯6ÿºýîýß¿úî«_|&EU×ÎduQ—çu}ûÕߺßgUZš¼v¹3®0æö«×Ü.Z/¼ÿs³~Ü>->¬>/îW‡Åv³ö¹Yxg5»Õ“Ïi²x÷î?»Õç‡Ãbó²ÈRO.׫‡Íï|†¿?›îWÿ³Ùοùè³Û§éóÛþÜ%8þ¸ÝÞÿ÷çf³øÓr³¿]ô{Ÿ&iî‹f·|þóêÞõ¬ý¢ëû#´:øϹ”

Is there something I can do here? And does someone know why this is happening to some participants’ data and not to others?

Thank you in advance for your help!

Are you opening the files with unicode utf-8 encoding?
I dont’t know about excel but you can change the encoding in libreoffice calc upon opening the csv file.

Yes, I tried that, but it did unfortunately not work.
