regsub $nick escape | char?

I got a script that removes users nick from a string with a certain trigger. The problem is that when the nick has | character in it, regsub removes the nick but leaves the | character.. Can I somehow go around this..?

the regsub I have is:

regsub -all -nocase "$nick" $nick_string "" nick_string

Because regsub uses regular expressions for it's matching mechanism,
the | is interpretted as "OR" by regsub.... these need to be escaped if you mean | literally...

ie.

Code: Select all

regsub -all "\\|" $nick "\\\|" nick2
regsub -all "$nick2" $nickstring "" nickstring

However, this can obviously avoided by using string map, as it
does not use regular expressions for its matching mechanism...
ie.

Code: Select all

set nickstring [string map "$nick {}" $nickstring]
