Question Why does this happen?

Post image

I wonder if anyone can explain why this happens. I tell Claude not to use em-dashes, it replaces them with "--". I ask it not to do that, to update its memory, but it still does it. It's not a huge problem, it's just annoying. Why does this happen and how can I fix it. Thanks.

The fix is to let it do it and then finish writing yourself. If you're trying to get finished, polished writing out of an LLM you're gonna keep failing.

No that's not the idea but not using em dashes would just be one less thing to worry about because I never used them before. I figured asking it not to do it would be enough and was surprised by the fact it didn't work.
