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("[^\\...
// strips off all non-ASCII characters text = text.replaceAll("[^\\x00-\\x7F]",""); // erases all the ASCII control characters text = text.replaceAll("[\\p{Cntrl}&&[^\r\n\t]]",""); // removes non-printable characters from Unicode text = text.replaceAll("\\p{C}",""); ...
System.out.println(URLEncoder.encode("This&string&has&ersands","UTF-8")); System.out.println(URLEncoder.encode("Thiséstringéhasé non-ASCII characters","UTF-8")); // System.out.println(URLEncoder.encode("this中华人民共和国","UTF-8")); } catch (UnsupportedEncodingException ex) {throw ...
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...
UNICODE_CASE Enables Unicode-aware case folding.(If your code is intended to be portable and uses case-insensitive matching on non-ASCII characters, you should use this flag.) UNICODE_CHARACTER_CLASS Enables the Unicode version ofPredefined character classesandPOSIX character classes.(启用预定义的字...
System.out.println(URLEncoder.encode("Thiséstringéhasé non-ASCII characters","UTF-8")); // System.out.println(URLEncoder.encode("this中华人民共和国","UTF-8")); } catch (UnsupportedEncodingException ex) {throw new RuntimeException(" ...
strings are encoded so that code point sequences that contain only non-null ASCII characters can ...

2.4.3 Non-ASCII characters For the remaining non-ASCII characters, either the actual Unicode character (e.g. ∞) or the equivalent Unicode escape (e.g. \u221e) is used, depending only on which makes the code easier to read and understand. Tip: in the Unicode escape case, and occasiona...
If you have a lot of non-ASCII characters to enter, you may wish to consider using Java’s input methods,discussed briefly in the JDK online documentation.
