How to validate .ttc files in Python

Python

def is_ttc(file_path: str) -> bool:
    """Check if file is a valid TTC by magic bytes."""
    signature = bytes([0x00, 0x01, 0x00, 0x00])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .ttc files in Node.js

Node.js

function isTTC(buffer: Buffer): boolean {
  const signature = Buffer.from([0x00, 0x01, 0x00, 0x00]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .ttc files in Go

func IsTTC(data []byte) bool {
    signature := []byte{0x00, 0x01, 0x00, 0x00}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}

Frequently Asked Questions

What is a .ttc file?

A .ttc file is a TTC file.

What are the magic bytes for .ttc files?

The magic bytes for TTC files are 00 01 00 00 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .ttc file?

To validate a .ttc file, read the first bytes of the file and compare them against the known magic bytes (00 01 00 00) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .ttc files?

The primary MIME type for .ttc files is application/x-font-ttf.

Is it safe to open .ttc files?

TTC (.ttc) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
