英文:
How do I get accented letter using substring()?
问题
I have the following string: ąbc. I'd like to get its first character, ie. ą. When I use the following code "ąbc".substring(0,1) I get the correct result using jshell. However, when using IntelliJ, I get a instead of ą. What's wrong?
以下是要翻译的代码部分：
// GIVEN
String string = "ąbc";
// WHEN
final String substring = string.substring(0, 1);
// THEN
assertThat(substring).isEqualTo("ą");

The following unit test works fine (in IntelliJ and in Maven):
@Test
void test() {
// GIVEN
String string = "ąbc";
// WHEN
final String substring = string.substring(0, 1);
// THEN
assertThat(substring).isEqualTo("ą");
}

这可能是由于您的IDE控制台未正确配置字符编码而引起的问题。
无论可见字符如何，您可以通过打印字符的十六进制值来确认它是否是正确的字符：
System.out.println(String.format("%04x", (int) "ąbc".charAt(0)));
该字符的结果应该是0105。
要显示正确的字符，您可能需要更改Intellij的主题或配置。
英文:
This is probably an issue with your IDE console not being configured correctly for the character encoding.
Regardless of the visible character you can confirm it is the right character by printing the hexadecimal value of the character:
System.out.println(String.format("%04x", (int) "ąbc".charAt(0)));
The result should be 0105 for that character.
To display the correct character you may need to change Intellij's theme or configuration.
