In a document being built with MikTeX, some auto hyphenation is being done with a "return" character (a left pointing arrow with a riser at the right end) instead of a hyphen. This seems to happen mostly in all-caps words, but it sometimes happens in initial-caps and lower case words. What could cause it?

I'm far from a TeX expert, but I learned that the hyphenation character can be changed by the \hyphenchar command. I assume that it can be changed for specific styles, which could account for the inconsistent appearance. However, I searched all of the source files I could find and I didn't find any instances of \hyphenchar.

    Welcome to TeX.SX! Without an example of code showing the issue it's really difficult to make a guess. – egreg Dec 2 '15 at 22:25

    it could be hyphenchar set to a different value (try \showthe\hyphenchar\font to see) It could (potentially) be that the font you are using has a return character in position 45, or it could be something else. With no example, impossible to guess. – David Carlisle Dec 2 '15 at 22:42
