I am using this regex for handling all sort of names:
String Regex_Name="^([A-Za-z]*|\\p{L})+([ ]*|[A-Za-z]*|[']*|\\p{L}*)+([\\s]?[A-Za-z]*)+[A-Za-z]$";
While running the code I am getting this error:
Unknown character property name {​​​​​​​L} near index 44
^[A-Za-z][[A-Za-z]*\p{​​​​​​​L}​​​​​​​*[,]?[ ]?[-]?[A-Za-z]+]+([ ]?[.]?[,]?[(]?[A-Za-z]+[)]?[-]?\p{​​​​​​​L}​​​​​​​*)+([,]?|[.]?)$
How can I solve the issue?
Use
String Regex_Name="^\\p{L}+(?:[’'-]\\p{L}+)*(?:\\s+\\p{L}+(?:[’'-]\\p{L}+)*)*$";
See proof.
The expression does not support shortened, abbreviated names, like John G. Smith.
