About

hallmark_tool Renders Unicode text to a PNG and reports, as JSON, which font drew each grapheme cluster. Use it to see what a character, emoji or string actually looks like: an unfamiliar or ambiguous codepoint, text versus emoji presentation (❤ vs ❤️), an emoji sequence, invisible characters, or how a specific font stack such as Fira Code Retina or Segoe UI Emoji draws text. Also reports which bundled fonts cover a character.

Use cases: presentations, design
