19 | | * The new string will have |
20 | | * - Newlines changed to spaces |
21 | | * - Consecutive spaces merged |
22 | | * - Trailing spaces removed |
23 | | * |
24 | | * It also allows to find the corresponding new positions of the input string in the stripped string. |
25 | | * This is important for attributes which might have to be imported, e.g., it helps to answer the question: |
26 | | * The 3rd character of the input string is subscript, which character in the output string is that? |
27 | | * |
28 | | * @note One leading whitespace is preserved. |
