[MiKTeX] Help needed: how to correctly incorporate calligra into MiKTex

[P Xu <sha...@ya...>]

Hello to you all out there.
 
Today, I tried to use a handwritten l in my latex file. I downloaded calligra.zip and unzipped it. I then copied the files to the subdirectory c:/localtexmf/fonts/calligra. Then I used MiKTex option to add this new set of fonts and refresh. Finally, I downloaded a calligra.sty file and placed it under the above subdirectory. It did not work, since the error message said that "calligra.sty does not exist". After moving calligra.sty to a subdirectory with other original MiKTex *.sty files, I did not get the error any more. What is strange is that when I used "\normalfont\calligra" to write "l", the whole ps and/or pdf files look like a messy: no proper text shown up, formulae strangely displayed here and there. In one word, a complete failure to produce the pdf file. 
 
Could anyone out there help? In fact, I simply want to see a handwritten l in one of my formulae. What is the correct way to get it?
 
Kindest greetings, with my thanks in advance.
