Re: [HOW] Changing FC3 file system to accept longer file names?

For what it's worth (and I know it's been worked out that this isn't the
problem for the Original Poster), I understand the limit to be 255
bytes. With UTF-8, a character can take up several bytes (up to four,
under current Unicode standards).

See man 7 utf8 for details.

So for example,
[james kendrick tmp]$ touch aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
[james kendrick tmp]$ touch ☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺
touch: cannot touch `☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺☺': File name too long

The "aaa..." filename is just 86 characters, so works fine (you can tell
because there's no error message).

The ☺ symbol takes three bytes, so a name consisting just of ☺ can only
have 85 characters (= 255 bytes).

Then you have to worry about combining characters...
