+libcurl is typically not aware of, nor does it care about, character
+encodings. \fIcurl_easy_escape(3)\fP encodes the data byte-by-byte into the
+URL encoded version without knowledge or care for what particular character
+encoding the application or the receiving server may assume that the data
+uses.

+The caller of \fIcurl_easy_escape(3)\fP must make sure that the data passed in
+to the funtion is encoded correctly.

 Added in 7.15.4 and replaces the old \fIcurl_escape(3)\fP function.
