Convert string to date

Hi, mcflurry 
In Power Query with TimeZone:

let
Date = Date.FromText(Text.BeforeDelimiter(Text.ReplaceRange([String],8,1,"T"),"T")),
Time = Time.FromText(Text.BetweenDelimiters([String], "-", "-")),
getTimeZone = Text.AfterDelimiter([String], "T"),
getPlusOrMinusZone = Text.Start(getTimeZone, 1),
GetHourOfZone = Number.FromText( Text.Middle(getTimeZone,1,2)),
GetMinuteOfZone = Number.FromText(Text.End(getTimeZone,2)),
DateTime = DateTime.From(Date & Time),
DateTimeZone = DateTime.AddZone(DateTime,GetHourOfZone,GetMinuteOfZone),
CompleteWithCheck = if getPlusOrMinusZone = "+" then DateTimeZone else DateTime.AddZone(DateTime,-GetHourOfZone,GetMinuteOfZone)

in CompleteWithCheck

Add New Column like this. "String" is your column with the provided date. Then just Change Type of the new column to "date" or "datetime" or "datetimezone".

Edit:
I enhanced the code to check whether it's "+" or "-".

Regional Settings is already to an European country.

Could you please help me on how to fix it with your code?

I guess it's this line, but i don't have the knowledge to achieve it... 

Date = Date.FromText(Text.BeforeDelimiter(Text.ReplaceRange([String],8,1,"T"),"T")),

I'm transforming the the original column with unicode format... and maybe it will work.

Yep, fixed that way, thanks.
