iCalendar（rfc2445）中的TEXT值应该冒号冒号吗？

Question

我从阅读规范（http://www.ietf.org/rfc/rfc2445.txt）的理解是，“：”字符应该而不是在文本值（例如DESCRIPTION）中转义。

从RFC：

The "TEXT" property values may also contain special characters that are used to signify delimiters, such as a COMMA character for lists of values or a SEMICOLON character for structured values. In order to
support the inclusion of these special characters in "TEXT" property
values, they MUST be escaped with a BACKSLASH character. A BACKSLASH
character (US-ASCII decimal 92) in a "TEXT" property value MUST be
escaped with another BACKSLASH character. A COMMA character in a
"TEXT" property value MUST be escaped with a BACKSLASH character
(US-ASCII decimal 92). A SEMICOLON character in a "TEXT" property
value MUST be escaped with a BACKSLASH character (US-ASCII decimal 92). However, a COLON character in a "TEXT" property value SHALL NOT be escaped with a BACKSLASH character.

我问这个，因为我收到的会议设备v8.7.1b63为Mac OS X的语法错误，由于该字符，但不为Windows版本的软件（相同的版本号）。它使我从我写的软件中产生的ics文件窒息。这是我的软件中的一个错误吗？

这是在接收到错误的iCalendar档案：

BEGIN:VCALENDAR 
VERSION:2.0 
PRODID:-//abc/abc//NONSGML v1.0//EN 
BEGIN:VEVENT 
UID:1234_abcd@abc.abc

\, viewing a presentation\, formatting\, finalizing a presentation and 
    delivering a presentation. 
END:VEVENT 
END:VCALENDAR 

注意的描述的第三行结肠。在这个冒号中添加斜线可以修复Mac上的问题，但根据标准，我认为这是不正确的。

感谢您的帮助！

这似乎是他们的软件中的错误。

"However, a COLON character in a "TEXT" property value SHALL NOT be escaped with a BACKSLASH character."

非常简单。

看看他们是否有任何补丁。 如果不是，请尝试联系他们并告诉他们。
