I have subtitles in English and Russian for a DVD project (two separate DVDs, one in each language), to be realized with Adobe Encore. The subtitles were done with Media Subtitler.
Everything went perfectly well with the English subtitles - with Media Subtitler, I converted the SubRip file into Adobe Encore (TXT) format, then imported the subtitles into Adobe Encore. There were no problems at all.
With the Russian subtitles: first of all there seems to be a bug in Media Subtitler, since when I tried to convert the SubRip file into Adobe Encore format, the Russian characters were lost and replaced by all sorts of strange characters. (Of course I checked all the settings within Media Subtitler - the Cyrillic character set, etc.). As soon as I re-opened, in Media Subtitler, the file I had just converted, the Russian characters were lost. Opening the file with Microsoft Word and selecting the "Cyrillic" format gave the same result, so it seems indeed to be a bug.
This bug I was able to get around by downloading a different program that correctly converted the Russian subtitles from SubRip to Adobe Encore format. Now when I opened the new Adobe Encore subtitle file in Media Subtitler, all the Russian text was there.
That problem being solved, I am faced with a new problem: Adobe Encore is unable to import this Adobe Encore file. This time I did not see the result personally as it is a colleague who is doing the work with Adobe Encore and I was not with him when he tried. He told me that the message he gets is that it is impossible to import the file, and it is necessary to save it in UTF-8 or UTF-16 format. I tried saving the file (using Microsoft Word) in Cyrillic (Windows) text format; trying to import it in Adobe Encore, my colleague said it gave him the same error message. Of course UTF-8 and UTF-16 are not going to work for Cyrillic characters.
