low surrogate - Details

• 
  Key Concepts: 
  Low surrogate is a term used in the Unicode Standard to refer to a specific range of code points. It is part of the UTF-16 encoding scheme, which is used by SAP to represent characters in its software. Low surrogates are code points in the range U+DC00 to U+DFFF, and they are used to represent characters that cannot be represented using a single 16-bit code unit. 
  
  How to use it: 
  Low surrogates are used in SAP software when a character cannot be represented using a single 16-bit code unit. In this case, two 16-bit code units are used, with the first one being a high surrogate and the second one being a low surrogate. The high surrogate is always in the range U+D800 to U+DBFF, while the low surrogate is always in the range U+DC00 to U+DFFF. 
  
  Tips & Tricks: 
  When working with low surrogates in SAP software, it is important to remember that they must always be paired with a high surrogate. If you encounter an isolated low surrogate, it will not be displayed correctly and may cause errors.
