No "official support ticket" that I'm aware of; just phpBB project members and phpBB project users contributing their time.
I had been able to save the current smilies configuration from my 3.0.14 board and load that configuration into my resulting 3.2.2 board without issue, which I'm assuming is similar to where your .pak came from. If your .pak came from an even earlier version of phpBB then maybe there are additional differences.
When I look at my .pak file with Notepad++, it's a file that doesn't begin with any byte order mark (BOM), and is using Unix-style line endings (LF) as opposed to Windows CR/LF. There does also happen to be a space character at the end of each line, after the comma that is at the end of each line. The encoding says it's UTF-8, but there aren't any characters in the file outside the normal ASCII range in my case.
That's all I can think to look for or describe as remarkable about the file, other than the data lines themselves which are presumably exactly as you would expect:
Code: Select all
'help.png', '32', '32', '1', 'question', ':?:',
I don't know how closely the format would be preserved if you attached your .pak to a post here (renaming to .txt if necessary), but I'm sure many could take a look in case something else unusual was apparent in the file you're actually attempting to use.
