iCalendar (rfc2445) 中的 TEXT 值中的冒号字符是否应该转义？
我通过阅读规范的理解（http://www.ietf.org/rfc/rfc2445.txt ）的一个问题是“:”字符不应该在像描述这样的文本值中被转义。
来自 RFC：
“TEXT”属性值也可能 包含特殊字符 用于表示分隔符，例如 值列表的逗号字符 或分号字符 结构化的价值观。为了
支持将这些特殊的 “TEXT”属性中的字符
值，它们必须用转义 反斜杠字符。反斜杠
字符（US-ASCII 十进制 92） “TEXT”属性值必须是
用另一个反斜杠逃脱 特点。
中的逗号字符 “TEXT”属性值必须被转义 带有反斜杠字符
（US-ASCII 十进制 92）。分号 “TEXT”属性中的字符
值必须用反斜杠转义 字符（US-ASCII 十进制 92）。 但是，“TEXT”中的冒号字符 属性值不应被转义 带有反斜杠字符。
我之所以问这个问题，是因为我在 Mac OS X 版 Meeting Maker v8.7.1b63 中收到了由于该字符导致的语法错误，但 Windows 版本的软件（相同版本号）却没有收到语法错误。我用我编写的软件生成的 ics 文件令人窒息。这是他们的我的软件中的错误吗？
这是收到错误的 iCalendar 文件：

请注意描述第三行的冒号。在这个冒号中添加斜杠可以修复 Mac 上的问题，但我认为根据标准这是不正确的。
感谢您的帮助！
My understanding from reading the specification (http://www.ietf.org/rfc/rfc2445.txt) is that the ":" character should not be escaped in text values like DESCRIPTION.
From the 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.
I ask this because I'm receiving syntax errors in Meeting Maker v8.7.1b63 for Mac OS X due to this character but not for the Windows version of the software (same version number). It's choking on ics files I'm generating from software I've written. Is this a bug in my software of theirs?
This is the iCalendar file that is receiving the error:

Note the colon on the third line of the description. Adding a slash to this colon fixes the problem on the Mac but I think this is incorrect according to the standard.

这似乎是他们软件中的一个错误。
非常简单。
看看他们是否有任何补丁。
如果没有，请尝试联系他们并告诉他们。
It appears to be a bug in their software.
Is pretty straightforward.
See if they have any patches.
If not, try to contact them and tell them about it.
