I have no idea what exactly you are doing, but ES Note Editor (that's what it's called, not a Text editor) is perfectly capable of editing this value to anything you want, no matter how many characters. I just tried it on my phone to confirm, simply out of curiosity. Same would be true for any other text editor. It's a plain text file, and unless you are using some custom editor designed for working with build.prop, which for some reason has constraints on some property values, you can do whatever you want.

To whom it may concern: STOP nagging about pressing the freakin' Thanks button!!! It is rude, stupid, and annoying as hell. I am not an idiot who needs a huge in-my-face reminder to press it, and I will press it when I feel thankful, not because you asked for it!
