Things to know about Azerbaijani
Azerbaijani is a Turkic language which is spoken in Azerbaijan and some of the surrounding areas. There are also many Azerbaijani speakers in Iran.
Typing Azerbaijani Characters
Azerbaijani has been written with a number of different alphabets in the past, but currently uses a variation of the Latin alphabet that includes several special characters. The most notable is ə, which is very common in Azerbaijani words. There are two methods for typing the special characters.
The simplest method is to use the character suggestions. To do so, type the base character for the letter you want (such as e for ə), then select the special character from the set of characters which appears.
The other method is to use the virtual keyboard with the layout set to Azerbaijani. (If necessary, you can change the layout by clicking 
and selecting an option in the Keyboard Language menu.)
Locate the character you want on the virtual keyboard, then click on it or press the corresponding key on your physical keyboard. Capital letters and certain punctuation marks, such as the question mark, are available by holding down the Shift key. Note, however, that the positions of some letters and punctuation marks are not the same as on the English keyboard, so you will need to look carefully as you type.
See Typing Accents and Special Characters for details on both typing methods.
Be aware that some older Azerbaijani speakers, especially those educated during the Soviet era, may be more familiar with the Cyrillic alphabet than the current Latin one.
