Convert string of ASCII values to general string
  I have been working on an issue for quite a while trying to figure out if this can be done natively in NSIS or if I will need to use something externally to solve my problem. What I need to do is convert a string of three-digit ASCII codes into a general string. For instance, I will need to convert "084069083084" into "TEST".

T=084
E=069
S=083
T=084

Any ideas if this is something that can be done in NSIS using base functions? I have been looking all over to no avail. Any hints would be extremely appreciated. Thanks!
