/ʒ/ in words and phrases derived from French

The consonant /ʒ/ appeared in English after the Old English period and it is still impossible to find in words that are originally Germanic. This post focuses not on well-known words containing /ʒ/, such as television, but more foreign-sounding and looking words. Note that the pronunciation is Anglicised according to RP rules: it is not original French pronunciation.
