What encoding does this use?
8-bit binary (one byte per ASCII character). For extended characters, UTF-8 code points are used, which may produce multi-byte sequences.
Can I decode binary without spaces?
Yes — the decoder handles both space-separated groups and a continuous binary string, as long as the total bit count is divisible by 8.
