Question

我正在创建一个Vim语法文件，我需要在iskeyword选项中添加一些字符。我无法从Vim帮助文件中找出它是如何工作的，但这是我目前所写的：

set iskeyword+=_,.,-,64,133,!,?,@,172,8743,8744,8853,8592,8593,8594,8595,8596

＃64和＃133是at符号和省略号。最后几个字符是¬，∧，∨，⊕，→，←，↓，↑和↔。

在所有这些字符中，只有_，。， - 和¬（＃172）似乎被识别为关键字字符。

还有什么我需要做的吗？或者Vim根本不支持超出Unicode特定点的关键字字符（但是at符号也没有被识别，并且肯定在ASCII中）？

感谢您的帮助！

iskeyword的帮助指向isfname的帮助，以回答您的所有问题：

[…]
Multi-byte characters 256 and above are always included, only the
characters up to 255 are specified with this option.
For UTF-8 the characters 0xa0 to 0xff are included as well.
[…]
The format of this option is a list of parts, separated with commas.
Each part can be a single character number or a range.  A range is two
character numbers with '-' in between.  A character number can be a
decimal number between 0 and 255 or the ASCII character itself (does
not work for digits).  Example:
[…]
If the character is '@', all characters where isalpha() returns TRUE
are included.  Normally these are the characters a to z and A to Z,
plus accented characters.  To include '@' itself use "@-@".  Examples:
    "@,^a-z"    All alphabetic characters, excluding lower
            case ASCII letters.
    "a-z,A-Z,@-@"   All letters plus the '@' character.
[…]

“此选项仅指定最多255个字符。”
“字符编号可以是0到255之间的十进制数”
“要包含'@'本身使用”@ - @“”

iskeyword中包含多字节字符已经在许多列表中进行了讨论，例如this one。
