Markdown to PDF (CJK Support)

Convert Markdown to professional PDFs with full Chinese/Japanese/Korean text support.

Why This Exists

Most Markdown-to-PDF tools break on CJK characters, require LaTeX, or need heavy dependencies. This skill uses reportlab for lightweight, reliable PDF generation that works on any server — including 2GB RAM VPS instances.

Usage

python3 {baseDir}/scripts/md_to_pdf.py input.md "Document Title" output.pdf

Features

✅ Full CJK text rendering (Chinese, Japanese, Korean)
✅ Markdown headings, bold, italic, bullet lists, code blocks
✅ Tables with proper column alignment
✅ Automatic page breaks and numbering
✅ Lightweight — runs on minimal servers (2GB RAM)
✅ No LaTeX, no wkhtmltopdf, no Chrome/Puppeteer needed

Supported Markdown Elements

# H1 through #### H4 headings
**bold** and *italic*
- bullet lists (nested supported)
| table | rows | (pipe-delimited tables)
`inline code` and code blocks
--- horizontal rules

Dependencies

pip3 install reportlab

Font Configuration

The script auto-detects CJK fonts in common locations:

/usr/share/fonts/ (Linux)
/System/Library/Fonts/ (macOS)

If no CJK font is found, it falls back to Helvetica (CJK characters will not render). Install a CJK font:

# RHEL/CentOS/Alibaba Cloud Linux
sudo yum install -y google-noto-sans-cjk-ttc-fonts

# Ubuntu/Debian
sudo apt install -y fonts-noto-cjk

Use Cases
