Abstract

A system and method for protecting text from unauthorized access. An original data set including a plurality of character code values is received, where each character code value corresponds to a respective character defined in a character definition standard. A new value corresponding to an undefined value within the character definition standard is determined for each character code value. An augmented code point-to-glyph mapping is created based on the new values with mappings between each new value and a glyph to render a character associated with the character code value. A new data set is created based on the data set and the augmented code point-to-glyph mapping by replacing character code values in the data with new values corresponding to the text character codes. The new data set and the augmented code point-to-glyph mapping are sent to a destination.
