英文:
what does `too short multibyte code string in regex` mean?
问题
我正在创建一个Sublime Text的语法高亮文件。然而，我遇到了一个我不太理解的错误。我有以下的正则表达式：
\x([0-9]|[A-F]|[a-f])([0-9]|[A-F]|[a-f])
当我尝试在Sublime Text中加载这个文件时，我得到了以下错误：
> Error in regex: too short multibyte code string in regex
> \x([0-9]|[A-F]|[a-f])([0-9]|[A-F]|[a-f])
我尝试通过谷歌搜索来理解这个错误的含义，但我只找到了以下相关的链接：
不幸的是，从这些链接中我只能确定这个错误很可能是由字符编码引起的[来自1和2]。我现在怀疑"\x"可能是问题所在，因为正则表达式中的其他部分都是正确的。如何转义这个字符和其他类似的字符？特别地，是否可以使用一个Golang脚本来清理正则表达式以解决这些问题？
英文:
I am creating a sublime text highlighting file. However, I am stuck with an error I don't fully understand. I have the following regex:
\x([0-9]|[A-F]|[a-f])([0-9]|[A-F]|[a-f])
When I try to load the file in sublime text, I get the error:
> Error in regex: too short multibyte code string in regex
> \x([0-9]|[A-F]|[a-f])([0-9]|[A-F]|[a-f])
I have tried Googling to understand what this error means, the only thing I have come across that is relavent are the following links:
0. github issue of the rubinius project
Unfortunately, from those links i could only determine that that error likely caused by a character encoding [ from 1 & 2]. I now suspect that "\x" might be the problem as everything else in that regex is fine. How does one escape that character and all others like it, in particular, can a golang script be used to sanitize regexes to get rid of such problems?

得分: 3
这意味着你忘记在\x中转义\了。
因此，它试图解析形式为\x1234的 Unicode 字符转义，但没有找到足够的数字。
英文:
It means that you forgot to escape the \ in \x.
Therefore, it's trying to parse a Unicode character escape of the form \x1234, and it didn't find enough numbers.
