Key $11 (=) not interpreted

[fjpa]

Looks like RPB PGN player does not interpret key $11 which is used to indicate that a position is even (=). The issue is documented in attached screen shot.

Fixed in version 4.2.1.

However, it seems that there is a confusion between NAGs $10 and $11 among chess softwares:

• According to the PGN specification (http://www6.chessclub.com/help/PGN-spec), $10 means "drawish position", while $11 means "equal chances, quiet position". No "official" symbol is however defined in the specification document.
• Chessbase seems to export symbol = as $11.
• SCID seems to export symbol = as $10.
• The Wikipedia page on NAG (https://en.wikipedia.org/wiki/Numeric_Annotation_Glyphs) indicates that symbol = is mapped as $10.
• etc...

Concerning RPB Chessboard, as of version 4.2.1, both $10 and $11 are rendered as symbol =.
