What do you think a fat letter is? If I were to guess, I'd say a bold letter. You know, like bold text on a screen.
The reading for this one is a bit odd. It combines the kun'yomi ふと from 太 with the on'yomi じ from 字. You learned both these readings with the kanji, so you should be OK here. You'll just have to remember it's a weird mix of kun'yomi and on'yomi. It kind of makes this word stand out… as if it were written in bold letters.
