Handle OS error 36 - File name too long

On many Linux systems, the maximum file name lenght
is 255 bytes. If the title contains UTF-8 characters, each
character may require more than 1 byte in the file name,
causing a title of 100 characters to actually exceed the 255
byte limit.

We handle this error and then use a much stricter file name format.
