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

*Text*
_Text_

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

*Text*
*Text*

The configured emphasis style can be a specific symbol to use (asterisk, underscore) or can require all emphasis matches the first emphasis (consistent).

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.
