如何从左到右的方向打印阿拉伯字符

Question

我有一系列英文和阿拉伯文字,应该以对齐的方式打印.

例如:

List<Character> ar = new ArrayList<Character>();
ar.add('?');
ar.add('?');
ar.add('?');

List<Character> en = new ArrayList<Character>();
en.add('a');
en.add('b');
en.add('c');

System.out.println("ArArray: " + ar);
System.out.println("EnArray: " + en);   

预期产出:

ArArray: [?, ?, ?] // <- I want characters to be printed in the order they were added to the list
EnArray: [a, b, c]

实际产量:

ArArray: [?, ?, ?] // <- but they're printed in reverse order
EnArray: [a, b, c]

有没有办法在从左到右的方向打印阿拉伯字符而不在输出之前明确地反转列表？

您需要在每个RTL字符之前添加从左到右的标记'\u200e'以使其打印LTR:

public String printListLtr(List<Character> sb) {
    if (sb.size() == 0) 
        return "[]";
    StringBuilder b = new StringBuilder('[');
    for (Character c : sb) {
        b.append('\u200e').append(c).append(',').append(' '); 
    }
    return b.substring(0, b.length() - 2) + "]";
}
