You're right - Amadeus is re-writing a pretty garbled version of the PNR - without getting proper documentation for the format I don't see how you can reliably parse the information.

All I can glean (by guesswork) if that the record you posted relates to two flights:

Tallinn to Vienna on flight no OV 0192 (Estonia Air) Departs 29th Aug 0725 Arrives 0845 (from U-001x))
Vienna to Ankara on flight no TK 8726 (Turkish Airlines) Departs 29th Aug 1030 Arrives 1400 (from H-019)

You could also try assuming that G-X gives departure and final destination airports (VIEANK = Vienna, Ankara)
No idea where the reservation number is.


FWIW:
Fare was 144 Euros (or 2255 Estonian Kroon @ 15.64660) (from K-F)

KFTF and TAX are obviously various taxes in Kroon (Airport tax, etc)
Q- is probably the fare expressed as 'Neutral unit of construction' where ROE is the exchange rate for Euros.
SSR is probably 'Special Service Request'

A bigger sample might provide a better guess :-{
