Just add an anchor to the URL:

final String markdown = "This is [*Sparta*](http://sparta.com)";
=>
final String markdown = "This is [*Sparta*](http://sparta.com#anchor)";

Missing post:

```java
  System.out.println("Hello world");
```
This is [Sparta](http://sparta.com#anchor)

translatingTexts

```_1_ <== (1)
_2_
```
This is [_3_](_4_#_1_) <== (1)

translatedTexts

```anchor <== (1)
System.out.println("Hello world");
```
This is [Sparta](http://sparta.com#anchor) <== (1)

@heyuxian, thank you for catching this. It is an omission in handling anchors for links which are not self-references to headings in the document. If the link has a page ref and an anchor then the anchor is left as the translation reference instead of being restored to original text.

I updated the code in the master branch and releasing a new version.

Fix for this is available. Repo updated, maven updated but may take a while to show up in maven central.
