可以使用文本编辑器(如Notepad++)来转换文件的编码,并去除BOM。 ## 3. 正则表达式检查非ASCII字符 在Java中,你可以使用正则表达式来检查字符串中是否存在非ASCII字符。以下是一个示例代码: ```java public class IllegalCharacterChecker { private static final Pattern NON_ASCII_PATTERN = Pattern.compile("[^\\...
When launching in integrated/external terminal, the debugger passes commands to vscode, and vscode assembles and sends it to the terminal. But if there's non-ascii char in code/path, the java process will have unexpected behavior, because of bad Unicode support in Windows. Either VS Code or...
