Decompression of string starting with '<'

Marka83

I've compressed following string using DeflateStream in C# :"<Some test string" Base64 output is this: swnOz01VKEktLlEoLinKzEsHAA== But this string won't inflate (or any other string which starts with < like html document). If I try with string "Some test string" its compressed to: C87PTVUoSS0uUSguKcrMSwcA and it works just fine.
