I notice discussion about "New syntax". My idea about this subject, hope useful, is: We can have default "special characters" set and alternative "special characters" defined for any row in tables where the default set interferes with content of rows. It is necessary to define a list of character set functionality, code, definition. When it is necessary, for some rows, it can be defined alternative "special characters" in one column as a string of characters (not used in text). The position in string is functionality code. mm
