IWebBrowser: How to specify the encoding when loading html from a stream?
- by Ian Boyd
Using the concepts from the sample code provided by Microsoft for loading HTML content into an IWebBrowser from an IStream using the web browser's IPersistStreamInit interface:
HRESULT LoadWebBrowserFromStream(IWebBrowser* pWebBrowser, IStream* pStream)
{
[snip]
}
How can one specify the encoding of the html inside the IStream? The IStream will contain a series of bytes, but the problem is what do those bytes represent? They could, for example, contain bytes where:
each byte represents a character from the current Windows code-page (e.g. 1252)
each byte could represent a character from the ISO-8859-1 character set
the bytes could represent UTF-8 encoded characters
every 2 bytes could represent a character, using UTF-16 encoding
In my particular case, i am providing the IWebBrowser an IStream that contains a series of double-bytes characters (UTF-16), but the browser (incorrectly) believes that UTF-8 encoding is in effect. This results in garbled characters.
