Hi,
if I URL-decode the first filter, it looks like this:

(1 = 1) AND (1 = 1 AND (region = 'JAPAC') AND (country = 'South Korea') AND
(state = 'Chungcheongnamdo [*Ch''ungch'ongnam-do*]'))

Only one of the single quotes has been doubled. If also the second is
repeated, as expected, then there is no error:

https://abbvie-ows.omnilocation-iot.com/geoserver/abbvie/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=asset_site&TILED=true&CQL_FILTER=(1%20%3D%201)%20AND%20(1%20%3D%201%20AND%20(region%20%3D%20%27JAPAC%27)%20AND%20(country%20%3D%20%27South%20Korea%27)%20AND%20(state%20%3D%20%27Chungcheongnamdo%20%5BCh%27%27ungch%27%27ongnam-do%5D%27))&TIME_=1583319334693&viewparams=&WIDTH=512&HEIGHT=512&CRS=EPSG%3A3857&STYLES=&BBOX=10018754.17139462%2C5009377.085697312%2C15028131.257091932%2C10018754.171394624

Hope this helps

Cheers
Andrea
