Inconsistent behavior between unknown command and unknown html entity

When having:
```
/**
 * an unknown command \unkn
 *
 * an unknown html entity \
 */
void fie();
```
we get the, correct, warnings:
```
 warning: Found unknown command '\unkn'
 warning: Unsupported symbol \ found
```
but contrary to ``unkn` the text for `\` is not echoed to the output.
