They can be:\n- Single characters (like \"a\", \"b\", \"c\")\n- Emojis (like \"✉️\", \"👋\")\n- Combining characters (like \"é\" which can be \"e\" + \"́\")\n- Complex sequences (like \"👨‍👩‍👧‍👦\" which is a family emoji)\n\nFor example, \"abc✉️\" contains 4 graphemes: \"a\", \"b\", \"c\", and \"✉️\".\n\n## Technical Details\n\n- **Frontend**: React 18.2.0 with TypeScript\n- **Backend**: Hono server for serving the app\n- **Styling**: TailwindCSS\n- **Grapheme Counting**: Uses `Intl.Segmenter` with `granularity: 'grapheme'`\n- **Platform**: Built for Val Town\n\n## Project Structure\n\n```\n├── backend/\n│ └── index.ts # Hono server entry point\n├── frontend/\n│ ├── components/\n│ │ └── App.tsx # Main React component with all logic\n│ ├── index.html # HTML template\n│ └── index.tsx # React entry point\n└── README.md\n```\n\n## Usage\n\n1. Enter text in the textarea\n2. View real-time statistics:\n - **Graphemes**: The number of visual units\n - **Characters**: The total character count\n - **Words**: The number of words\n3. Try the example texts to see complex grapheme counting in action\n\n## Example Results\n\n| Text | Graphemes | Characters | Words |\n|------|-----------|------------|-------|\n| \"abc✉️\" | 4 | 6 | 1 |\n| \"Hello World! 👋\" | 13 | 15 | 2 |\n| \"café 🍵\" | 6 | 8 | 2 |\n| \"👨‍👩‍👧‍👦\" | 1 | 7 | 1 |\n\n## Browser Compatibility\n\nThe app uses `Intl.Segmenter` which is supported in:\n- Chrome 87+\n- Firefox 102+\n- Safari 15+\n- Edge 87+\n\nFor older browsers, it falls back to character counting.\n\n## Development\n\nThis is a Val Town project. The main entry point is `backend/index.ts` which serves the React application.\n\nTo run locally with Deno:\n```bash\ndeno run --allow-net --allow-read backend/index.ts\n``` ","createdAt",["D",1751246952429],"branchVersion","branchId","b3e8f022-554f-11f0-8094-f69ea79377d9","id","b3e8b56c-554f-11f0-8094-f69ea79377d9","graphemeCounter",["D",1751246125761],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","","imageUrl","7777b241-b5c2-407f-9330-0a51c837a3a2","pinnedFileId","a09f5a68-5551-11f0-baea-f69ea79377d9","pinPreview",true,"pinMigrated","screenshotVersion","likeCount",3,"orgId","bb3998b1-c8e5-40e9-a23f-1834cb719fe5","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_94":93,"_101":97},"org",{"_94":93,"_95":-5,"_96":97,"_18":52,"_98":99,"_100":24},"branch",{"_13":83,"_31":84,"_40":39,"_85":41,"_86":-5,"_87":-5,"_88":-5,"_89":-5,"_90":-5,"_91":42,"_92":93},"isOwned",17,"main","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","dpip","handle","displayName","avatar","https://img.clerk.com/eyJ0eXBlIjoicHJveHkiLCJzcmMiOiJodHRwczovL2ltYWdlcy5jbGVyay5kZXYvdXBsb2FkZWQvaW1nXzJ6OWNXUldad0VRdjFUVE1Nc3lqU0RLR3lWUSJ9","tier","free","canRestrictVals","profileImageUrl","branchName","adoptOrgId",{"_40":41,"_31":42,"_35":215,"_44":-5,"_45":24,"_46":47,"_48":47,"_49":50,"_51":-5,"_18":52,"_53":54,"_55":56,"_57":56,"_58":-5,"_59":60,"_61":62,"_63":-5,"_64":-5,"_65":-5,"_66":-5,"_67":68,"_69":68,"_70":71,"_72":71,"_73":71,"_74":68,"_75":68,"_76":216,"_78":217,"_80":218,"_82":24},"tree",[162,164,168,169],"files",[162,163,164,165,166,167,168,169],"counts",{"_152":131,"_153":143,"_154":131,"_155":156,"_157":158},"contents",[123,124,125,126],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_40":146,"_31":147,"_29":148,"_128":-5,"_38":39,"_37":149,"_129":56,"_35":150,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_26":151},{"_40":140,"_31":141,"_29":142,"_128":-5,"_38":39,"_37":143,"_129":56,"_35":144,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_26":145},{"_40":134,"_31":135,"_29":136,"_128":-5,"_38":39,"_37":60,"_129":56,"_35":137,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_26":139},{"_40":127,"_31":27,"_29":30,"_128":-5,"_38":39,"_37":14,"_129":24,"_35":130,"_13":131,"_32":20,"_33":34,"_23":24,"_132":-5,"_26":133},"a0a57970-5551-11f0-a0e9-f69ea79377d9","parentId","latest",["D",1751246952429],0,"label",[27],"a077c76e-5551-11f0-b44b-f69ea79377d9","shared","a077c8cc-5551-11f0-b44b-f69ea79377d9",["D",1751246952134],"directory",[135],"a057a09c-5551-11f0-bda1-f69ea79377d9","frontend","a057a16e-5551-11f0-bda1-f69ea79377d9",1,["D",1751246951920],[141],"a0684ee2-5551-11f0-a3c1-f69ea79377d9","backend","a0684f96-5551-11f0-a3c1-f69ea79377d9",2,["D",1751246952032],[147],"pulls","branches","forks","envVars",{"_159":131,"_161":131},"connections",{"_159":131,"_160":131},"count","unfilledCount","emptyCount",{"_40":146,"_31":147,"_29":148,"_128":-5,"_38":39,"_37":149,"_129":56,"_35":212,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_171":213,"_26":214},{"_40":204,"_31":205,"_29":54,"_128":148,"_38":39,"_37":206,"_129":24,"_35":207,"_13":131,"_32":191,"_33":208,"_23":24,"_132":209,"_171":210,"_26":211},{"_40":140,"_31":141,"_29":142,"_128":-5,"_38":39,"_37":143,"_129":56,"_35":201,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_171":202,"_26":203},{"_40":196,"_31":195,"_29":188,"_128":142,"_38":39,"_37":197,"_129":56,"_35":198,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_171":199,"_26":200},{"_40":185,"_31":186,"_29":187,"_128":188,"_38":39,"_37":189,"_129":24,"_35":190,"_13":131,"_32":191,"_33":192,"_23":24,"_132":-5,"_171":193,"_26":194},{"_40":177,"_31":178,"_29":179,"_128":142,"_38":39,"_37":180,"_129":56,"_35":181,"_13":131,"_32":20,"_33":182,"_23":24,"_132":-5,"_171":183,"_26":184},{"_40":134,"_31":135,"_29":136,"_128":-5,"_38":39,"_37":60,"_129":56,"_35":174,"_13":131,"_32":138,"_33":-5,"_23":24,"_132":-5,"_171":175,"_26":176},{"_40":127,"_31":27,"_29":30,"_128":-5,"_38":39,"_37":14,"_129":24,"_35":170,"_13":131,"_32":20,"_33":34,"_23":24,"_132":-5,"_171":172,"_26":173},["D",1751246952429],"children",[],[27],["D",1751246952134],[],[135],"a0960daa-5551-11f0-8cb4-f69ea79377d9","index.html","a0960e68-5551-11f0-8cb4-f69ea79377d9",5,["D",1751246952331],"\n\n \n \n \n Grapheme Counter\n \n\n \n \n\n \n \n\n \n \n \n

\n What are graphemes?\n

\n Graphemes are the smallest units of a writing system. They can be\n single characters, emojis, or combinations of characters that form\n a single visual unit. For example, \"abc✉️\" contains 4 graphemes:\n \"a\", \"b\", \"c\", and \"✉️\".\n
