Setting the MIME Text Charset (such as utf-8, iso-8859-1, etc.)

See more MIME Examples

Demonstrates how setting the Charset property controls the character encoding used for the text body in a MIME message. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const mime = try chilkat.Mime.init();
    defer mime.deinit();

    // Set the MIME body using some 8bit non-us-ascii characters:
    mime.setBody("á, é, í, ó, ú");

    // Set the Content-Type
    mime.setContentType("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.
    mime.setEncoding("quoted-printable");

    // Set the Charset to utf-8
    mime.setCharset("utf-8");

    // Examine the MIME:
    std.debug.print("{s}\n", .{try mime.getMime(alloc)});

    // 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";
    mime.setCharset("iso-8859-1");

    // Get the MIME again...
    std.debug.print("{s}\n", .{try mime.getMime(alloc)});

    // 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
