The answer is "no" only for text-based web formats. But web formats also include many binary formats used as containers for multiple internal contents, and each one, if it is plain-text may have its own local encoding, even if there's a single encoding used for the transport enveloppe (e.g. a Binary-64 encoded container will use a plain-text external format, for transporting multiple data parts. Once the parts are separated from the envoloppe format, and Base-64 encoding returns to binary format, the internal structure may have its own metadata types and encodings.
Media files such as videos may contain multiple streams, e.g. one for each language embedded for subtitling, and each language version may have its own encoding. Some media file formats were designed for the web and standardized (e.g. MPEG files which are containers for multiple streams, that are eigher fully independant, or mutually synchronized on reference frame numbers or timestamps). 2013/8/28 Phillips, Addison <[email protected]> > What kind of document do you mean? > > For Web formats (HTML, etc.), the answer is "no". > > Addison > > Addison Phillips > Globalization Architect (Amazon Lab126) > Chair (W3C I18N WG) > > Internationalization is not a feature. > It is an architecture. > > > > > > -----Original Message----- > > From: [email protected] [mailto:[email protected]] On > > Behalf Of Costello, Roger L. > > Sent: Wednesday, August 28, 2013 12:07 PM > > To: [email protected] > > Subject: Can a single text document use multiple character encodings? > > > > Hi Folks, > > > > Can a single text document use multiple character encodings? > > > > For example, can some text be encoded as UTF-8 while other text is > encoded as > > UTF-16 - within the same document? > > > > /Roger > > > > > >
