Letter Blocks [ehlphabet] provides 26 uppercase letters from the Roman Alphabet, the Arabic Numerals 0-9, and a small selection of symbols. Included from the original mod is a letter machine to convert blank Ehlphabet Blocks into letter/symbol blocks. Blank blocks and the Letter Machine are both craftable! Unused letters can be crafted back into blank blocks, and blank blocks can be crafted back into paper.
