On line 134 of the file named CnInetUtils.pas begins the code for EncodeURL function.

Line 142 reads -

    if (URL[i] in UnsafeChars) or (URL[i] >= #$80) or (URL[1] < #32) then

I believe that should be -

    if (URL[i] in UnsafeChars) or (URL[i] >= #$80) or (URL[i] < #32) then
                                                                               ^
Nice work. I really wish there were some documenation that I could read. I only speak English.

You are right. We'll write more English documents in furture.
