"Treating Unicode character as whitespace"/"Invalid character in source file" warning in Xcode
提问by Tamás Sengel
When typing a spacecharacter in Xcode, a warning appears sometimes:
space在 Xcode 中输入字符时，有时会出现警告：
Treating Unicode character as whitespace
将 Unicode 字符视为空格
or
或者
Invalid character in source file
源文件中的无效字符
If I re-write the character, the warning disappears. What causes this?
如果我重新编写字符，警告就会消失。这是什么原因造成的？
回答by Tamás Sengel
That happens to me when I type too fast and accidentally hold down Altwhile pressing down Space. This creates a non-breaking space (0xA0) which is not recognized as a valid space character by Xcode.
当我打字太快并Alt在按下时不小心按住时会发生这种情况Space。这会创建一个不间断的空格 ( 0xA0)，Xcode 不会将其识别为有效的空格字符。
For a (hacky) solution, I've remapped this combination to Insert Tabinside Xcode's Preferences/Key Bindings, so it enters a tabulator character instead.
对于（hacky）解决方案，我已将此组合重新映射到Xcode 的Preferences/Key Bindings 中的Insert Tab，因此它输入了制表符字符。
