The thing about fencing is that it basically evolved from the general idea of swords as a form of self-defense, not swords as a tool of war, and pure effectiveness wasn't the only thought there.
In fact the term fencing as we use it today specifically referred to rapiers from the start, and rapiers were fashion as much as they were tools. They were designed to go well with fancy outfits and weren't even necessarily designed to kill people so much as to win duels, which it was great at due to it's light weight (plus, taking a big ol' killin' sword would probably be looked down upon, even though someone totally might die either way).
If I were making a character with a background in fencing who planned on going on adventures, I'd have them grab an estoc as it's essentially a specialized longsword. You want something that can make a big enough wound to drop someone quickly, sturdy enough to pierce armor, and an estoc fits those requirements. Another option would be a backsword as George Silver preferred it as a general self-defense weapon, if you're not expecting to fight armored opponents much or at all.
Yeah, this is a pretty good overview of the situation as it stands now.
BUT somehow I think I found a solution for myself in the hour since I posted it, AsciiDoc seems rad as hell. Very Markdown-like but geared more towards document writing and conversion to other "publishable" formats with features like automatic ToCs, citations, character conversion to more "literary" equivalents like emdash and more proper quotation marks, etc., just more complete in general where Markdown is for quick n' dirty comments and forum posts. I'm super glad that I found it. Apparently some O'Riley books were written in it.
