ST_AsEncodedPolyline('SRID=4326;LINESTRING EMPTY') fails

ST_AsEncodedPolyline('SRID=4326;LINESTRING EMPTY') fails:

[local] gis@gis=# select ST_AsEncodedPolyline('SRID=4326;LINESTRING EMPTY');
ERROR:  XX000: getPoint2d_cp: point offset out of range
LOCATION:  pg_error, lwgeom_pg.c:162
Time: 0,263 ms

It should be empty string. Reverse works:

[local] gis@gis=# select ST_AsText(ST_LineFromEncodedPolyline(''));
┌──────────────────┐
│    st_astext     │
├──────────────────┤
│ LINESTRING EMPTY │
└──────────────────┘
