Another option is to use a different font for the italic, bold, and bold-italic, such as one of the resident fonts already on the T1. The results may look a little weird, but at least you'll end up with bold, italic, etc.
For example, to use the Amasis files found on the T1, use the following code
(note the different file-path!)
Code:
@font-face { font-family: serif; font-weight: normal; font-style: normal; src: url(res:///ebook/fonts/../../mnt/sdcard/fonts/sylfaen.ttf);}
@font-face { font-family: serif; font-weight: normal; font-style: italic; src: url(res:///ebook/fonts/AmasisMTW1G-Italic.otf);}
@font-face { font-family: serif; font-weight: bold; font-style: normal; src: url(res:///ebook/fonts/AmasisMTW1G-Bold.otf);}
@font-face { font-family: serif; font-weight: bold; font-style: italic; src: url(res:///ebook/fonts/AmasisMTW1G-BoldItalic.otf);}
If you use the above, normal words will appear in Sylfaen, and italic, bold, and bold-italic will use Amasis.
If you want to use another font that you add to the same font folder that you put sylfaen, you would use this code:
Code:
@font-face { font-family: serif; font-weight: normal; font-style: normal; src: url(res:///ebook/fonts/../../mnt/sdcard/fonts/sylfaen.ttf);}
@font-face { font-family: serif; font-weight: normal; font-style: italic; src: url(res:///ebook/fonts/../../mnt/sdcard/fonts/FONTNAME.ttf);}
@font-face { font-family: serif; font-weight: bold; font-style: normal; src: url(res:///ebook/fonts/../../mnt/sdcard/fonts/FONTNAME.ttf);}
@font-face { font-family: serif; font-weight: bold; font-style: italic; src: url(res:///ebook/fonts/../../mnt/sdcard/fonts/FONTNAME.ttf);}
Or, of course, you can choose a different font-family altogether that includes all four fonts styles.
