Pupilla Multi-Language PDF Feature

How to Add Multiple Language PDFs

To add multiple language versions of a PDF, use the pdfs field instead of the single pdf field in your preprint’s front matter:

Example Configuration:

---
layout: preprint
title: "Your Paper Title"
authors:
  - Author Name
pdfs:
  - language: "English"
    url: "/assets/pdfs/your-paper-en.pdf"
    flag: "🇺🇸"
  - language: "Italiano" 
    url: "/assets/pdfs/your-paper-it.pdf"
    flag: "🇮🇹"
  - language: "Français"
    url: "/assets/pdfs/your-paper-fr.pdf"
    flag: "🇫🇷"
---

Field Explanations:

• language: The display name for the language (can be in the native language)
• url: Path to the PDF file
• flag: Emoji flag representing the language/country (optional - system will auto-detect common ones)

Supported Auto-Flags:

The system automatically detects flags for common languages:

• English → 🇺🇸
• Italiano/Italian → 🇮🇹
• Deutsch/German → 🇩🇪
• Español/Spanish → 🇪🇸
• Catalan → 🏴󠁥󠁳󠁣󠁴󠁿
• 日本語/Japanese → 🇯🇵

Migration from Single PDF:

Old format:

pdf: /assets/pdfs/paper.pdf

New format:

pdfs:
  - language: "English"
    url: "/assets/pdfs/paper.pdf"
    flag: "🇺🇸"

Both formats are supported simultaneously.
