iCalendar（rfc2445）中的TEXT值應該冒號冒號嗎？

Question

我從閱讀規範（http://www.ietf.org/rfc/rfc2445.txt）的理解是，「：」字符應該而不是在文本值（例如DESCRIPTION）中轉義。

從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.

我問這個，因爲我收到的會議設備v8.7.1b63爲Mac OS X的語法錯誤，由於該字符，但不爲Windows版本的軟件（相同的版本號）。它使我從我寫的軟件中產生的ics文件窒息。這是我的軟件中的一個錯誤嗎？

這是在接收到錯誤的iCalendar檔案：

BEGIN:VCALENDAR 
VERSION:2.0 
PRODID:-//abc/abc//NONSGML v1.0//EN 
BEGIN:VEVENT 
UID:1234_abcd@abc.abc 
DTSTART:20091022T133000 
DTEND:20091022T150000 
SUMMARY:Special Topics in Power Point

ands-on workshop will provide you with experience in the following: wh 
at's new in PowerPoint 2007\, presentation basics\, working with text 
\, viewing a presentation\, formatting\, finalizing a presentation and 
    delivering a presentation. 
END:VEVENT 
END:VCALENDAR 

注意的描述的第三行結腸。在這個冒號中添加斜線可以修復Mac上的問題，但根據標準，我認爲這是不正確的。

感謝您的幫助！

這似乎是他們的軟件中的錯誤。

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

非常簡單。

看看他們是否有任何補丁。 如果不是，請嘗試聯繫他們並告訴他們。
