When we place docs from our editors into our ID layout (2015 CC) we run into two consistent problems:
If the doc is a .doc or .docx it will only place the first line, the rest of the file does not show.
If the doc is in .txt format, strange Au' characters are inserted into the text.
How should we handle these files properly to avoid these issues?
Your first problem sounds like there is formatting applied preventing the line from breaking and it goes into overset. It could be as simple as No Break is applied as a default, or it could be hyphenation not allowed and all the spaces are non-breaking, or it could be something to do with keep options. The best way to diagnose is to open the story in Story Editor and look at the text immediately following the overset marker for a clue.
The second problem sounds like the text file is using an old font with different character mapping for PC and Mac.
Thank you Mr. Spier !
