windows - Powershell not splitting string returned from function -

i trying import csv contains fictional places , hours each day of week fictional places open.

the hours 5:00-4:00 format. have spaces. created function remove spaces. after function run, appears powershell can't run further operations on returned string (i.e. -split).

the csv:

node,sat,sun,mon,tue,wed,thu,fri pizzaplace,9:00 – 4:30,0,8:00-3:30,7:00 – 10:00,10:00 – 4:00,10:00 – 4:00,10:00 – 4:00 bigpharma,0,5:00 – 4:00,7:00-6:00,7:00-6:00,0,0,7:00-6:00 greenhouse,12:00-8:00,0,12:00-7:30,12:00-7:30,12:00-7:30,12:00-7:30,12:00-7:30 portapoty,12:00-8:00,closed,10:00-6:00,10:00-7:30,10:00-6:00,10:00-7:30,10:00-6:00 

the ps1 script:

function unk-ampm ($openstr) {     $openstr -replace " "; }  $csvinputs = import-csv samphours.csv;  $srprbn = "our hours for"; $srpran = "are";  $dswed = "wednesday";  foreach ($csvline in $csvinputs) {      $retailer = $csvline.node;      [string] $openwed = unk-ampm $csvline.wed;      write-host "value of openwed before split: "$openwed;      $openweda = $openwed -split "-";      write-host "value of openweda[0]: "$openweda[0];     write-host "value of openweda[1]: "$openweda[1];      if ($openweda[0] -eq 0 -or $openweda[0] -eq 'closed') {         $ohswed = "closed";     } else { $ohswed = $openweda[0] + " " + $openweda[1]; }      write-host $srprbn $retailer $srpran $ohswed "on" $dswed;  } 

and results:

value of openwed before split:  10:00–4:00 value of openweda[0]:  10:00–4:00 value of openweda[1]:   our hours pizzaplace 10:00–4:00  on wednesday  value of openwed before split:  0 value of openweda[0]:  0 value of openweda[1]:   our hours bigpharma closed on wednesday  value of openwed before split:  12:00-7:30 value of openweda[0]:  12:00 value of openweda[1]:  7:30 our hours greenhouse 12:00 7:30 on wednesday  value of openwed before split:  10:00-6:00 value of openweda[0]:  10:00 value of openweda[1]:  6:00 our hours portapoty 10:00 6:00 on wednesday 

the – in entries spaces not hyphens (u+002d), dashes (u+2013)

you'll see if data has been copied text processor "automagical" formatting (like word example).

use "punctuation, dash" unicode category match , split both kinds:

$openstr -split '\p{pd}'
