Summary : 
      This SAP Note addresses display issues in texts containing a mix of Hebrew or Arabic and Latin characters, outlined as appearing in a disordered structure due to the Unicode Bidirectional (BIDI) Algorithm. This algorithm, defined by the Unicode Consortium, arranges text based on character directionality (LTR for Latin and RTL for Hebrew/Arabic), yet struggles with context-dependent characters like digits and punctuation. SAP UIs use this standardized algorithm, which sometimes leads to non-intuitive displays, especially with numbers and mixed scripts. Solutions include avoiding mixed character types and using BIDI formatting characters.
