Powershell - converting hex from the registry key -

i have following output mru list. how can convert string or ascii characters?

'gp "hkcu:\software\microsoft\windows\currentversion\explorer\comdlg32\lastvisitedpidlmru"'

18 : {80, 0, 120, 0...}
5 : {50, 0, 109, 0...}

assuming gp "hkcu:\software\microsoft\windows\currentversion\explorer\comdlg32\lastvisitedpidlmru"

gives :

pspath       : microsoft.powershell.core\registry::hkey_current_user\software\microsoft\windows\currentversion\explorer\comdlg32\lastvisitedpidlmru psparentpath : microsoft.powershell.core\registry::hkey_current_user\software\microsoft\windows\currentversion\explorer\comdlg32 pschildname  : lastvisitedpidlmru psdrive      : hkcu psprovider   : microsoft.powershell.core\registry mrulistex    : {14, 0, 0, 0...} 11           : {114, 0, 117, 0...} 9            : {69, 0, 120, 0...} 19           : {83, 0, 107, 0...} 10           : {78, 0, 79, 0...} 17           : {123, 0, 57, 0...} 15           : {115, 0, 108, 0...} 7            : {123, 0, 57, 0...} 4            : {118, 0, 109, 0...} 21           : {109, 0, 115, 0...} 22           : {100, 0, 101, 0...} 24           : {123, 0, 55, 0...} 8            : {123, 0, 69, 0...} 0            : {123, 0, 69, 0...} 5            : {123, 0, 66, 0...} 12           : {83, 0, 110, 0...} 20           : {123, 0, 55, 0...} 23           : {83, 0, 99, 0...} 2            : {65, 0, 99, 0...} 16           : {110, 0, 111, 0...} 1            : {105, 0, 101, 0...} 18           : {75, 0, 105, 0...} 6            : {99, 0, 104, 0...} 13           : {123, 0, 55, 0...} 3            : {123, 0, 54, 0...} 14           : {123, 0, 57, 0...} 

you can try:

[system.text.encoding]::unicode.getstring((gp "hkcu:\software\microsoft\windows\currentversion\explorer\comdlg32\lastvisitedpidlmru")."11") 

this not good, can help
