1. A system for testing the display of bi-directional language script prior to translation in an application under test, the system comprising: a unidirectional to right-to-left character code point mapping, each unidirectional character in said mapping having a corresponding right-to-left character code; a pseudo-translator configured to produce a pseudo-translation by reversing characters of an input string and mapping said reversed characters to right-to-left character code points according to said code point mapping; and, a plurality of unidirectional language glyphs, each of said glyphs corresponding to a same one of said right-to-left character code points as had been used by said pseudo-translator to produce said pseudo-translation; wherein a combination of said pseudo-translation and said glyphs when rendered by an application under test simulates right-to-left character rendering in said application under test such that a resultant output is visually similar to said input string.
