Interestingly enough, most people will be able to understand exactly what you wrote there. People can easily recognize common words "by shape". They only ever have to look at the first and last letters.
I'm not saying people won't notice there's something wrong with what you wrote. They will. But they'll be able to understand you perfectly despite that.
I'm aware people can understand that, but it's certainly not as easy as the properly formed words. I used that technique to make sure my point was carried across.
