issue in creating a add link to a document content type on a doc lib name with , / special characters

hi,

i am having a  requirement to create/use "add link to a document" content type for a item in the document library.

so i got  the code from below site :

http://howtosharepoint.blogspot.in/2010/05/programmatically-add-link-to-document.html

my issue is, if teh document  library names are single words - like MOM, model, procedures etc this  functionality is working fine and i am able to view the link to a document as an item. 

but when the doc lib name contains special characters like , or  /  , this link to a  document  content type functionality is NOT working.

can anyone pls point me whether this is the  actual  issue ? ie, if  the doc lib name contains special chars  like , or /  my

add link to a document wont work? is there any restrictions/limitations for doc lib names in SharePoint ?

for eg: my doc lib names are :

1) Report and analysis, Data

2) form / template

3) map/ plot

help is highly appreciated!
