If title too long, inaccurate title passed around

sounds good, could we add a comment to add it explaining why we need to do that?

I just added that in and committed it to all d5, d6 + added it into d7. thanks.

Sorry to open it, but I realized, the substr is not a solution for utf8 strings. I attached a patch, it uses truncate_utf8() to truncate the title to 255 character not substr().

Patch is for 7.x-1.x version.

Patch for 6.x-1.x.

need change:

$node->title = substr($node->title, 0, 255);

to

$node->title = mb_substr($node->title, 0, 255);

is good work.

Please, use drupal_substr().

It was very hard to find a reason of PDO exception which was caused by this bug.

This could cause a data-loss in titles so major

Annoying bug. Please commit the simple patches.

"truncate_title_utf8_aware-937086-4.patch" applies successfully.
And truncate_utf8() is better solution
