Markdown Bold Lint

Detects bold rendering breakage in Markdown when a bold run ends with certain symbols and is immediately followed by CJK particles without spacing.

Features

• Warns only for patterns that are known to break in real renderers.
• Detects bold text ending with symbols like ), ], ", ,, ., ~, #, +, &, @, $, ^, =, |, §, ※, •, …, ·, -, 、, 。, / when CJK text follows without a space (including common fullwidth punctuation variants like ！？，：；％, ／, ）, 】).
• Warns when underscore-bold (__...__) is immediately followed by CJK text.
• Warns about invisible control characters (U+0000~U+001F, excluding tab/newline).

Fix Suggestions

• Move the trailing symbol outside bold.
• Include the particle in bold.
• Insert a space after bold.
• Prefer bolding inside surrounding punctuation to avoid awkward spacing.
