vim crashes because of conceal "f"

[FireyFly]

For one reason or another, vim crashes when I try to insert the "f" character functions are concealed into, or if I try to open the javascript.vim file. I assume this is not the case for you, since you presumably wrote the file in vim. :)

Can you confirm that this does not happen to you? For me, vim crashes with the following message:

Vim: Caught deadly signal FPE
Vim: Finished.

This applies to both vim and gvim.

It didn't happen to me. Probably something about your environment? I'm using ubuntu 11.04 with manually compiled vim 7.3.

Or maybe it's with the encoding. Try running this on your console, and make sure it says utf-8 unicode:

file after/syntax/javascript.vim

And try this on your .vimrc:

set encoding=utf8
set fileencoding=utf8

Hey, it looks like you're right.

I did some research.. first of all, I tried searching in "kcharselect", KDEs charmap utility, for things like "italic f", but I couldn't find anything interesting. The best hit I got was "ƒ", "latin small letter f with hook", which apparently is sometimes used as a function symbol. It's really ugly in DejaVu Sans Mono though, so I didn't want that.

Then I played around with charCodeAt for a while, but it only gave me char codes pointing to strange characters..
Then, when nothing else worked, I opened the javascript.vim file in a hex editor and checked on Wikipedia how UTF-8 works.. and after some tinkering I found the character is actually U+1D453... Lo and behold, there's actually such a character: http://www.fileformat.info/info/unicode/char/1d453/index.htm

Unfortunately, setting encoding and fileencoding to utf8 didn't help.. I'm using vim 7.3.353, installed from a binary package from Arch Linux' repos, and (g)vim still crashes. Do you have any other ideas? Perhaps I should try to manually compile vim from their dev repo.
