standards - 冒号字符是否应该在 iCalendar (rfc2445) 的 TEXT 值中转义？

Question

我阅读规范( http://www.ietf.org/rfc/rfc2445.txt )的理解是“:”字符应该 不是 被转义为文本值，如描述。

来自 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.

我问这个是因为我在 Mac OS X 的 Meeting Maker v8.7.1b63 中收到语法错误，因为这个字符而不是软件的 Windows 版本(相同的版本号)。我从我编写的软件生成的 ics 文件令人窒息。这是我的软件中的错误吗？

这是收到错误的 iCalendar 文件:

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

请注意说明第三行的冒号。向这个冒号添加斜线可以解决 Mac 上的问题，但我认为根据标准，这是不正确的。

谢谢你的帮助!

Answer 1

这似乎是他们软件中的错误。

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

很简单。

看看他们有没有补丁。
如果没有，请尝试与他们联系并告诉他们。
