Bug 341209

vim rc

I do not know if it's a bug or a feature, but it does not happen with xterm so I decided to post it.

In vim when we type Alt+L in insert mode it goes to normal mode. To avoid this behavior according to http://vim.wikia.com/wiki/Fix_meta-keys_that_break_out_of_Insert_mode I added in my ~/.vimrc these lines:
'''
" fix meta-keys which generate <Esc>a .. <Esc>z
let c='a'
while c <= 'z'
  exec "set <M-".toupper(c).">=\e".c
  exec "imap \e".c." <M-".toupper(c).">"
  let c = nr2char(1+char2nr(c))
endw
'''
In xterm the above works, but in Konsole when I type Alt+J or +K or +L I get Ê Ë Ì  respectively which is not what I want. 

I encounter this problem because I want to be able to write with "polymorphic Alt Key Macros" as described in 3.10.1 at http://vim-latex.sourceforge.net/documentation/latex-suite.html

So when I open a .tex file with 

vim test.tex

and I type i to go into insert mode and then left parenthesis and then Alt+L like:

(<<<press Alt+L>>>

I want to get (as vim-latex-suite dictates):

\left(\right)<++>

Instead, the Alt-Key binding does not work and I get an accented "I":

(Ì 


I attach my ~/.vimrc for easier reproducibility.

Thanks!
