ffa7f9b482 Changed the literal rune maps in simple.go to use hex numbers rather than character codes. 
Go sometimes subsitutes literal character codes (e.g. '\u2206') with other runes. This doesn't
happen if the literal is written as a number (e.g. 0x2206 ). I am not sure why Go does this.

This change builds the full maps from source files which are included in the commit.
