Original Pull Request: https://github.com/ollama/ollama/pull/11372

State: closed
Merged: No

When the AI generates large amounts of text and/or code blocks, they also produce large amounts of non printable characters. A mixture of this python doesn't like in the python Ollama framework which leads to issues which can't be resolved by the user. This is because of the way the AI calls the tool through the tool function interface where no parsing or removal of these non printable characters can occur before the tool is called. Then when python sees it as an argument it panics and throws a error.

I have provided some code below which should remove these characters before it is parsed into the tool as an argument.

I apologize if this is not correct but i at least wanted to try to do something to help fix it instead of just reporting the error itself. It passed all of the checks so thats a win. Let me know if i need to change anything else or if i have edited the wrong part of the codebase.

Thanks - Cassidy
