FS#13156 - Creating of talk files fails ungracefuly when encounting unspeakable text.

Rockboxutility barfs while creating talk files if it encounters unpronouncable charicters (japanese kanji) and does not continue afterwords resulting in talk files not being copied to the player.

The result of this is an invalid wav file wich the the encoder bails out on and the process aborts.

I suggest ignoring failed encoded files and continuing encoding and copying the files that suceeded.

Looks like changing if(m_talkList[i].encoded on line 245 in file /rockbox/rbutil/rbutilqt/base/talkfile.cpp to true will fix the problem.

Creating a japanese voice file works fine for me with espeak and espeak-ng, fails with flite and festival. So this is related to the actual TTS used, and as far as I understand the problem is that festival fails on the text.

While ignoring the failed ones for talk files might be an option (assuming you only have a few with characters triggering this problem) this completely fails for voice files, since the relevant strings wouldn't be voiced at all, even not as english fallback.

For now the best solution is to use a different TTS – someone familiar with festival would need to give that a closer look.
