# Why is the # character duplicated in footnotes?

I've run into a weird issue related to footnotes.

When I compile the document I pasted below, the "regular" #import statement is shown exactly as it appears in the source code. However, when I use the exact same bit of text in the footnote, an additional # is inserted with no apparent reason, causing "##import" to be shown in the produced document.

Can someone enlighten me as to what is going on here?

• Fn 1. of the documentation: For example, \mintinline works in footnotes! The main exception is when the code contains the percent % or hash # characters, or unmatched curly braces. – Alan Munn Aug 16 '18 at 15:53
• Use \# to typeset an octothorpe, not a bare # (which is a special character to TeX). (Edit: Maybe I don't understand how \mintinline works. @AlanMunn seems better informed.) – Harald Hanche-Olsen Aug 16 '18 at 15:53
• @HaraldHanche-Olsen Escaping the character doesn't work. The result in my case becomes "\#include" – Bartvbl Aug 16 '18 at 15:55
• @AlanMunn Well, I guess that explains it. – Bartvbl Aug 16 '18 at 15:55
• Yes, I see that now. (See my update on the comment you responded to. I really had no idea what the minted package does. Sorry about the noise.) – Harald Hanche-Olsen Aug 16 '18 at 15:56

This is a known limitation of the \mintinline command which is mentioned in Fn 1 of the documentation:
For example, \mintinline works in footnotes! The main exception is when the code contains the percent % or hash # characters, or unmatched curly braces.
Since the minted authors are clearly aware of it, I suspect it's not an issue that they are planning to solve.
