I copied the file to another directory using the copy command. When I opened the file that was in the second directory I got the following popup:</div><div class="" style="font-family: TimesNewRomanPSMT;"><br class=""></div><div class="" style="font-family: TimesNewRomanPSMT;"><img apple-inline="yes" id="BD332BE4-503D-441B-B58C-0E48730CDFB6" class="" src="cid:F48B39C0-F3EA-47EB-B1A8-FE9D1291804F@hsd1.mn.comcast.net."></div><div class="" style="font-family: TimesNewRomanPSMT;"><br class=""></div><div class=""><font style="font-size: 14px;" class="">[This file was opened with</font></div><div class=""><font style="font-size: 14px;" class=""> IsoLatin9 encoding.</font></div><div class=""><font style="font-size: 14px;" class=""><br class=""></font></div><div class=""><font style="font-size: 14px;" class=""> The file could not be opened with Unicode (UTF-8)</font></div><div class=""><font style="font-size: 14px;" class=""> encoding because it was not saved with that</font></div><div class=""><font style="font-size: 14px;" class=""> encoding.

The first TeX file was started around January 23, 2024 and last edited on February 4. I updated TeXShop to v. 5.27 on, or shortly after February 12, and I'm wondering if that update I made to TeXShop was the cause of the popup. Otherwise, I don't know why the popup appeared.</div><div class="" style="font-family: TimesNewRomanPSMT;"><br class=""></div><div class="" style="font-family: TimesNewRomanPSMT;">I responded with the OK button, and I was able to continue without any further problems.</div><div class="" style="font-family: TimesNewRomanPSMT;"><br class=""></div><div class="" style="font-family: TimesNewRomanPSMT;">Bill</div></body></html>
