Unicode Text Formatter

An Obsidian plugin that transforms selected text into Unicode Mathematical Alphanumeric Symbols — Sans-Serif Bold, Italic, and Bold-Italic — plus Circled and Fullwidth characters — for use in social media posts.

Features

• Unicode Bold — converts letters and digits to sans-serif bold (𝗔𝗕𝗖 / 𝗮𝗯𝗰 / 𝟬𝟭𝟮)
• Unicode Italic — converts letters to sans-serif italic (𝘈𝘉𝘊 / 𝘢𝘣𝘤)
• Unicode Bold Italic — converts letters to sans-serif bold italic (𝘼𝘽𝘾 / 𝙖𝙗𝙘)
• Unicode Fullwidth — converts letters and digits to fullwidth forms (ＡＢＣ / ａｂｃ / ０１２)
• Unicode Circled — converts letters and digits to circled forms (ⒶⒷⒸ / ⓐⓑⓒ / ①②③)
• Remove Unicode Formatting — converts any formatted Unicode characters back to plain ASCII
• Convert List Bullets to Arrow — prefixes every selected line with → , stripping any leading * marker first
• Convert List Bullets to Em Dash — prefixes every selected line with — , stripping any leading * marker first
• Convert List to Numbered (Slash) — numbers every selected line as 1/ item, 2/ item, ..., stripping any leading * marker first
• Convert List to Numbered (Parentheses) — numbers every selected line as (1) item, (2) item, ..., stripping any leading * marker first
• Convert Markdown to Post Format — converts a Markdown selection to LinkedIn/Facebook-ready text: ## headings → bold, **bold** → Unicode bold, _italic_ → Unicode italic, - list items → — em-dash bullets
• Non-mapped characters (punctuation, spaces, emoji, etc.) are passed through unchanged

Usage

2. Open the Command Palette (Ctrl/Cmd + P)
3. Run one of:
   • Format as Unicode Bold

   • Remove Unicode Formatting — reverses any of the above back to plain ASCII
   • Convert List Bullets to Arrow — prefixes every line with → (strips * if present)
   • Convert List Bullets to Em Dash — prefixes every line with — (strips * if present)
   • Convert List to Numbered (Slash) — numbers every line as 1/ item, 2/ item, ... (strips * if present)
   • Convert List to Numbered (Parentheses) — numbers every line as (1) item, (2) item, ... (strips * if present)

The selected text is replaced in place.
