Strings Conversion Helper

On this page:

• Goal
• Convert a String128 string to an UTF-8 string
• Convert an UTF-8 string to a String128 string

Goal

The SDK provides some helpers functions to convert from UTF16 (use in VST 3 interfaces) to UTF8 (used by std::string).

Here some code examples:

Convert a String128 string to an UTF-8 string

#include "public.sdk/source/vst/utility/stringconvert.h"

//...
if (auto hostApp = Steinberg::U::cast<IHostApplication> (hostContext))
{
    Vst::String128 name;
    if (hostApp->getName (name) == kResultTrue)
    {
        // Here we convert a Vst::String128 to a std::string (UTF8)
        std::string str = VST3::StringConvert::convert (name);
        //...
    }
}

Convert an UTF-8 string to a String128 string

#include "public.sdk/source/vst/utility/stringconvert.h"

//...
std::string str ("My Title");
Vst::String128 vstStr;
VST3::StringConvert::convert (str, vstStr);
