TTE
application/octet-stream
Magic Bytes
Offset: 0
00 01 00 00 00
The TTE file format is a TrueType Extension container developed by Microsoft Corporation for use within the Windows operating system. This format primarily stores user-defined characters created through the Private Character Editor, allowing for the integration of custom glyphs and symbols into existing font libraries. As a legacy format, it is considered safe for general use, though its relevance has diminished with the widespread adoption of modern Unicode standards and OpenType technology.

Python

"""Check if file is a valid TTE by magic bytes."""
signature = bytes([0x00, 0x01, 0x00, 0x00, 0x00])
with open(file_path, "rb") as f:

How to validate .tte files in Node.js
Node.js

const signature = Buffer.from([0x00, 0x01, 0x00, 0x00, 0x00]);
return buffer.subarray(0, 5).equals(signature);
}
Go
