Found the problem... actually had to start deleting features one at a time... and each feature analyzed... the '=' from 'Încărcături maxime:+3.3 V - 20 А,+5 V - 20 А,+5 V Standby = 3 А,-12 V - 0.3 A;' is with some error... but it seems that the error is not from the 'equal' symbol itself, but rather this symbol got copied with error from the source (maybe something deep, like some 'bits' in the symbol got altered and Thirtybees didn't recognize it... )
Something similar I had with the 'non-breaking space'... visually it's the same, but on bit level it might be different...
