I was on one of my doctors' patient portal a few minutes ago, and went into the "edit my profile" screen. Among the options was a pull-down list for primary language. Always curious, I opened the list to see what options were available.
To my surprise, the programmers must have found a list of EVERY known language...including 1600's AD English and 1100 AD Italian. I went in search of my favorite test case, and sure enough Klingon was there. Qapla' !
Seems like a bad thing to say to a doctor, but HeghluʼmeH QaQ jajvam.
Of course I selected Klingon as my primary language and saved the preference.....
