:I wrote the previous question from a cybercafe and I did not log on because I was in a hurry. The book is titled "Dictionary of the Turkic Languages", by Kurtuluş Öztopçu et al, ISBN 0-415-16047-2. It was first published in 1996 and reprinted in 1999 but the copy I have is from 2006 (I took it from Ilford Public Library and it says it was transferred to digital printing in 2006) which means it should/could have been corrected if the spelling in Turkmen were wrong or had become out of date. According to the book "Azerbaijani, Turkmen and Uzbek are given in both their official Cyrillic and Latin scripts" (page x) but not a single "ý" or "ň" can be seen in the many Turkmen entries of the book. In page ix it can be read "Responsibility for the content and editing of the individual languages was undertaken as follows: [...] Turkmen: Youssef Azemoun, Turkmen expert.". I would appreciate if anybody could tell me how official are the spellings ñ & ÿ versus ň & ý. Thanks
