 This checker detects the use of ftell() on a file open in text (or translate) mode. The text mode is not consistent
  in between Linux and Windows system and may cause ftell() to return the wrong offset inside a text file.
 
+See section 7.21.9.4p2 of the C11 standard regarding the ftell function states for a text stream:
+
+- For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

 This warning helps improve code quality by:
 - Making the intent clear that the use of ftell() in "t" mode may cause portability problem.
