Syntax:
{attribute 'monitoring_encoding' := 'UTF8'}
Insertion location: Above the variable declaration
Example
PROGRAM PLC_PRG

strDat : STRING := 'abc';
attribute 'monitoring_encoding' := 'UTF-8'}
strVarUtf8: STRING := UTF8#'你好,世界!ÜüÄäÖö';
{attribute 'monitoring_encoding' := 'UTF-8'}
str1: STRING := UTF8#'AÄyyy';
{attribute 'monitoring_encoding' := 'UTF-8'}
str2: STRING := UTF8#'AÄxxxÜÜÜ';
