If you edit an USFM file with Word and want to use it in translationCore (or another USFM program), you need to first save as a “.txt” file. Word will give a popup warning that you may lose formatting. At this point you want to change from the default encoding. Select “other encoding” and then select “Unicode (UTF-8)“ and then save. You can see the steps here https://support.3playmedia.com/hc/en-us/articles/227730088-Exporting-a-UTF-8-txt-file-from-Word
