In the US those "symbols" would be for non-polarized capacitors. A polarized symbol would have a small + sign above the upper bar. The high capacitance numbers would likely indicate electrolytics though. The 1uF could be non-polarized, but the 220uF would have to be a polarized electrolytic. For some non-polarized capacitors that are made up of wound layers of foils and insulation, the curved line indicates the outer foil.
But then, that's just my 50 some years of experience.

50 years? you must be what, 70 years old now?
not that it's dire, it's admirable, that's all.
Many foreign people who come to this forum call them "capacitaters".
Old geezers call them "condensers".
