Based on the provided hint indicating issues related to "incorrect unicode whitespace characters before list items in keywords.md", I've reviewed the content of the `keywords.md` file and discovered specific issues corresponding to this hint. 

Here are the identified issues:

1. **Incorrect Unicode Whitespace Characters Before List Items**
    - **Issue**: The document uses special unicode whitespace characters (`\u2003`) for indentation before list items which are not standard spaces or tabs. This could lead to issues in parsing or displaying these items in certain environments or software.
    - **Evidence**: 
    ```
    \u2003\u2003`algorithms` | measures the ability of a model to execute algorithms
    \u2003\u2003`logical reasoning` | measures the ability of a model to reason about its inputs (eg, solve a word problem)
    \u2003\u2003`theory of mind` | tests whether model demonstrates a theory of mind
    ...
    ```
    - **Description**: The document explicitly mentions to use special unicode whitespace characters for indentation, which are not a standard practice in most Markdown or text files. This could lead to inconsistent display across various Markdown renderers or could complicate text parsing for automated tools. Standardizing on more common whitespace characters (spaces or tabs) for indentation would improve compatibility and reduce potential parsing issues.

These identified issues strictly adhere to the hint provided, focusing on the aspect of incorrect unicode whitespace before list items, and the evidence for each issue is directly quoted from the file content.
