# 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
- editor.getSelection() / editor.replaceSelection()
- this.addCommand({ id, name, editorCallback })
- this.addRibbonIcon()

## Commands to register
1. unicode-formatter:bold        "Format as Unicode Bold"
2. unicode-formatter:italic      "Format as Unicode Italic"
3. unicode-formatter:bold-italic "Format as Unicode Bold Italic"
