Limitations

Short texts unreliable
Texts shorter than ~20 characters produce unreliable results — trigram analysis needs sufficient sample
What to do instead: Provide at least 30+ characters for reliable detection
Similar languages may be confused
Closely related languages (e.g., Norwegian/Danish/Swedish, Serbian/Croatian) may be confused
