I speak two languages (English and Russian) and have never found their name to be awkward. This is the first time, actually, that I've seen somebody say they don't like their name.

Curious on what languages have a hard time saying Libre.

Every latin-derived language (which are most of the western languages) can pronounce it naturally, and even English speakers can approximate it well enough to be understood (even though they're incapable of pronouncing the non-retroflex `r`).
