Oracle Message O2U-00206 - Some characters in a type name were not legal identifier characters

ERRORSome characters in a type name were not legal identifier characters
CAUSEOne or more characters in the name of a user-define type could not be translated to a character that can appear in a C or C++ identifier, such as a letter, an underscore, or a digit. The characters that could not be translated were replaced with underscores.
ACTIONSpecify an explicit translation for the type name in the INTYPE file, or just use the translated type name with added underscores.
