A heads-up that there appears to be a bug in the latest edition of Microsoft Word that affects the original Gentium font. When using this font with AutoCorrect turned on, straight quotes are not changed to curly quotes, and a letter ‘i’ at the beginning of a word will be capitalised. You end up with something like this:
This began happening for me in Microsoft Word build 12430.20288. Should anyone else raise this with Microsoft, it might help to quote my ticket number reporting this issue, which is #18826628.
It doesn’t seem possible to work around the curly quotes probably (other than adding curly quotes manually with ALT+0145 to ALT+0148). You can work around the upper-case ‘I’ problem by going to Options -> Proofing -> AutoCorrect Options -> AutoCorrect, and deleting the single ‘i’ from the list at the bottom.
