Re: [chessx-developer] Text in angle brackets in comments is not displayed

[Fex X. <fs...@gm...>]

Thanks for responding to my email. Let me clarify a few things from my last
email. The issue was that text in a move comment displayed in angle
brackets was not displayed in the game browser.

1. These are not XML tags. They are also not HTML tags. This is ordinary
ASCII text in which some strings are enclosed in angle brackets. They
should be displayed like any other ASCII text comment. It is clear these
cannot be HTML or XML tags. For one thing, there is no end tag!

2. I did not mean to suggest that CQL is embedded into a comment. CQL is
distributed with a sample PGN database, used in the CQL examples for
documentation. The sample database CQL uses in its documentation can be
downloaded here: http://www.gadycosteff.com/cql/pgn/sample.pgn . That PGN
file (mainly excerpts from the Heijden database) has examples of comments
containing angle brackets.

To clarify, my request is this: display the text of a comment.

(Obviously, if ChessX makes exception for text enclosed in HTML tags, that
is fine. That does not apply in this case. These strings are obviously not
HTML and so they should be displayed as normal text).

I believe this is the intent of the PGN specification, which allows ASCII
text in comments. The Heijden PGN database has been under development for
over 20 years and displays fine in ChessBase, HiArcs and probably others.
We do not want a situation where a conformant, ASCII, PGN file looks fine
in some PGN viewers but in which comments are invisible in other PGN
viewers. That is confusing for users and database creators.
