markdownlint/doc-build/md050.md

This rule is triggered when the symbols used in the document for strong do not match the configured strong style:

**Text**
__Text__

To fix this issue, use the configured strong style throughout the document:

**Text**
**Text**

The configured strong style can be a specific symbol to use ("asterisk", "underscore"), or can require that usage be consistent within the document.

Note: Emphasis within a word is restricted to "asterisk" in order to avoid unwanted emphasis for words containing internal underscores like_this_one.

Rationale: Consistent formatting makes it easier to understand a document.
