# Sample output:

# Host: www.chilkatsoft.com

# Content-Length: 79

# <pre>tytul=3DPrzyk%C5%82ad&amp;tresc=3DPrzyk%C5%82ad
# %82oszenie</pre>
# --------------------------------------------------

# We can see by the %C5%82 that utf-8 was sent, because %C5%82 is the 2-byte representation of a particular Polish char.

# -----------------------
# However.. we can change the charset used for the HTTP request by specifying the request object's charset.
