[Shily]

Here's what I did. I only tested one file, but it turned out really well. Hope this helps.

1. I opened the Vietnamese file I wanted to read, which was in DOC format. I used "Save As" and chose the type to be Web Page, Filtered (aka HTML format).

2. I followed the instruction in this post, using the HTML file that I had just saved. Apparently the Calibre in the post was of an older version, but it's very easy to figure out what goes where.

3. Extra info: The font I used was Times New Roman, very easy to read on the reader. You can find all four of them in Control Panel\Fonts, just copy and paste but do not rename them. Since Times New Roman has an extra bold italic type, I added a new section for it in the CSS, just in case. Below is my CSS for your reference.

@font-face {
font-family: "Times New Roman";
font-weight: normal;
font-style: normal;
src: url(res:///Data/fonts/times.ttf);
}

@font-face {
font-family: "Times New Roman";
font-weight: bold;
font-style: normal;
src: url(res:///Data/fonts/timesbd.ttf);
}

@font-face {
font-family: "Times New Roman";
font-weight: normal;
font-style: italic;
src: url(res:///Data/fonts/timesi.ttf);
}

@font-face {
font-family: "Times New Roman";
font-weight: bold;
font-style: italic;
src: url(res:///Data/fonts/timesbi.ttf);
}

body {
font-family: "Times New Roman", serif;
}
