Project: Obsidian Unicode Text Formatter Plugin

Goal

Transform selected text in the Obsidian editor into Unicode Mathematical Alphanumeric Symbols (Sans-Serif Bold / Italic / Bold-Italic) for use in LinkedIn and Facebook posts.

Architecture

• TypeScript, Obsidian Plugin API only, zero external dependencies
• Four files to implement: src/unicode-maps.ts, src/formatter.ts, src/commands.ts, main.ts
• Build tool: esbuild (already configured in the sample plugin template)

Key Unicode Blocks

• Sans-Serif Bold uppercase: U+1D5D4–U+1D5ED
• Sans-Serif Bold lowercase: U+1D5EE–U+1D607
• Sans-Serif Bold digits: U+1D7EC–U+1D7F5
• Sans-Serif Italic uppercase: U+1D608–U+1D621
• Sans-Serif Italic lowercase: U+1D622–U+1D63B
• Sans-Serif Bold-Italic uppercase: U+1D63C–U+1D655
• Sans-Serif Bold-Italic lowercase: U+1D656–U+1D66F

Obsidian API used

• this.addCommand({ id, name, editorCallback })
• this.addRibbonIcon()
