For users who sign up directly, the files they add to their Kerika boards are stored by us using the Box Platform.

The Box Platform has some limitations that you may bump into:

• Certain characters are not allowed in file names, e.g. “/”. We noticed people were running into this problem, most probably because they were hitting the wrong keys inadvertently when renaming files.

  Kerika is going to take of this silently from now on: if you try to rename a file using a character like “/” that Box can’t handle, Kerika will silently ignore that character in your renaming action.

• File names can’t be more than 260 bytes. For people using English and similar languages, this generally means a file name cannot be more than 260 characters (with each character requiring one byte of storage). But for most Asian languages, e.g. Thai or Japanese, one character may require two bytes of storage, because the size of the alphabet is much larger than the Roman alphabet used by English.

  This means that in some languages, file names may have to be much shorter, depending upon how many bytes are needed for storing each character, which in turn depends upon the size of their alphabets.

  Some folks from Thailand were running into this problem: Kerika will start detecting this better, and provide more useful error messages
