Previously returned new CharArrayReader(value.toCharArray()), which allocates a char[] proportional to the string length (2 * n bytes). StringReader wraps the String directly with no extra allocation.

No benchmark written: the allocation is trivially O(n) and the fix is mechanical. Visible in -prof gc as reduced char[] allocation under any workload that calls getCharacterStream().
