Recommendation
Whether asterisks or underscores are used affects how and whether emphasis works. Underscores are sometimes used to represent normal underscores inside words, so there are extra rules in markdown to support that. Asterisks are not used in natural language, so they don’t need these rules, and thus can form emphasis in more cases. Asterisks can also be used as the marker of more constructs than underscores: lists. Due to having simpler parsing rules, looking more like syntax, and that they can be used for more constructs, it’s recommended to prefer asterisks.Fix
remark-stringify
github-remark-stringify formats emphasis with
asterisks by default.
Pass emphasis: '_'
to always use underscores.Examples
