(Unicode C) Setting the MIME Text Charset (such as utf-8, iso-8859-1, etc.)Demonstrates how setting the Charset property controls the character encoding used for the text body in a MIME message.
#include <C_CkMimeW.h> void ChilkatSample(void) { HCkMimeW mime; // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. mime = CkMimeW_Create(); // Set the MIME body using some 8bit non-us-ascii characters: CkMimeW_SetBody(mime,L"á, é, í, ó, ú"); // Set the Content-Type CkMimeW_putContentType(mime,L"text/plain"); // Set the Content-Transfer-Encoding to "quoted-printable" // so it's easy to see the bytes used to encode each character // (i.e. it will be easy to see that utf-8 uses 2-bytes for // non-us-ascii characters such as "á", whereas a character // encoding such as iso-8859-1 will use one byte per character. CkMimeW_putEncoding(mime,L"quoted-printable"); // Set the Charset to utf-8 CkMimeW_putCharset(mime,L"utf-8"); // Examine the MIME: wprintf(L"%s\n",CkMimeW_getMime(mime)); // The MIME should look like this: // Content-Transfer-Encoding: quoted-printable // Content-Type: text/plain; charset="utf-8" // // =C3=A1, =C3=A9, =C3=AD, =C3=B3, =C3=BA // Now change the Charset to "iso-8859-1" CkMimeW_putCharset(mime,L"iso-8859-1"); // Get the MIME again... wprintf(L"%s\n",CkMimeW_getMime(mime)); // Now the MIME should look like this: // Content-Transfer-Encoding: quoted-printable // Content-Type: text/plain; charset="iso-8859-1" // // =E1, =E9, =ED, =F3, =FA CkMimeW_Dispose(mime); } |
