Special Characters Break Formatting

http://forum.videolan.org/viewtopic.php?f=14&t=111577

I've noticed a rendering issue with a handful of files with SSA/ASS (embedded) subtitles.

Subtitle lines with special characters in (e.g. ) render perfectly up to and including said character, but the remainder of the line loses any custom formatting it otherwise had.

Example Correctly rendered in MPC-HC

An affected video file (see e.g. 21s, 1m16s & 1m28s)

I couldn't find any settings that seemed relevant to this to fiddle with, and I still get the error even if I perform a full reset of the preferences. It's also present with or without HW Accelerate enabled, though admittedly this particular file is Hi10P. A log file should be attached to this ticket, but there's no indication of the malfunctioning subtitles as far as I can tell.

I'm currently running Windows 8 x64, with up-to-date chipset and graphics drivers, using the 32-bit build of VLC 2.0.7, though this also happens with the experimental 64-bit build.

I'm not sure if this bug is also present in the Linux or Mac versions, I'm not currently in a position to check.

On advice from the forums, I submitted a report to libass directly.

Within a couple of hours, someone appears to have located the problem and written a patch for it in their own libass git clone.

Hopefully this gets into their main tree soon, and therefore into VLC. :D

kthxbye

Nice, it just means I need to update libass as soon as there is a release :)

changed the description

Just thought I'd point out here, new version of libass (0.10.2) appeared recently, so the next repackage/rebuild of VLC (depending on platform) should have this problem fixed. :)
