Please notice that browsers do not work the same way as text editors or VTrain, for example.

Actually, HTML pages are nothing but plain text files (".txt") with a 'fake' extension (.htm). For backward compatibility, the 'source code' of an HTML page is usually written in ANSI (Western), and a header in that code tells the browser which encoding scheme it must use to display the page. Just open an HTML page with Notepad to see something like this:

<META HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=iso-8859-1">

This is a simple and elegant approach, but since this header is set once for the whole page, multilingual documents are not possible, unless you use the Text only (Unicode) format.

For this reason, most editors use the rich text format ".rtf" instead of ".txt", which stores information about encodings along with font data. This is the case of Microsoft Word and VTrain, but since VTrain 4.5 is not Unicode-enabled yet, non-Western glyphs get lost when you save Decks of flashcards (".vok" files), and when you export a ".vok" Deck to a ".txt" file with VTrain 4.5, it is saved as Text only (ANSI).

Please take into account that VTrain 5.0 will be Unicode-compatible, so the issues you describe will be gone.
