(€) can take up 3 bytes in UTF-8 encoding.This creates a "mismatch" that causes the SSD firmware to reject the character or truncate the password, potentially locking you out. ⚠️ The Risk of Using It
But the ATA Security spec (T13) expects a password of 1–32 bytes. Sending 3 bytes for one symbol either: why can't i use the euro (€) symbol in my ssd password?
The Euro symbol presents a technical anomaly in older encoding systems. (€) can take up 3 bytes in UTF-8 encoding
In the early stages of booting, most systems rely on basic character encoding standards, typically (American Standard Code for Information Interchange). In the early stages of booting, most systems
The one exception: If you set the password using a manufacturer’s tool (e.g., Samsung Magician), it might accept UTF-8. But then the BIOS pre-boot will fail because it uses a different encoding (often CP437 or ISO-8859-1) where € is missing.
