Unicode Text Formatter

An Obsidian plugin that transforms selected text into Unicode Mathematical Alphanumeric Symbols — Sans-Serif Bold, Italic, and Bold-Italic — for use in LinkedIn and Facebook 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)
• Non-mapped characters (punctuation, spaces, emoji, etc.) are passed through unchanged

Usage

1. Select text in the editor
2. Open the Command Palette (Ctrl/Cmd + P)
3. Run one of:
   • Format as Unicode Bold
   • Format as Unicode Italic
   • Format as Unicode Bold Italic

The selected text is replaced in place with its Unicode equivalent.
