[Using Sakai] Short URLs for files with non ASCII characters

[Rafael Morales Gamboa]

I searched the url_randomised_mappings_t, ran the results through od, and
found that

0000000   1   1  \t   H   a   q   X   O   C  \t   h   t   t   p   :   /
0000020   /   v   i   r   t   u   a   l   .   c   u   d   i   .   e   d
0000040   u   .   m   x   :   8   0   8   0   /   a   c   c   e   s   s
0000060   /   c   o   n   t   e   n   t   /   g   r   o   u   p   /   8
0000100   b   f   7   3   c   8   c   -   0   9   6   8   -   4   9   1
0000120   4   -   8   c   4   4   -   9   1   8   d   7   6   f   a   3
0000140   8   9   6   /   I   n   t   r   o   d   u   c   c   i 363   n
0000160       a       S   a   k   a   i       -       P   e   r   s   p
0000200   e   c   t   i   v   a       d   e   l       U   s   u   a   r
0000220   i   o   .   p   d   f  \n

So the URL is stored using #f3 (octal 363) for the 'ó' (accute o). In other
words, Sakai/MySQL is using the ISO 8859-1 encoding instead of UTF-8 to
store shortened the URL.
