Left Trimming by character (any number)

CREATE FUNCTION [dbo].[LTRIMCHAR] (@Input NVARCHAR(max), @TrimChar CHAR(1) = ',')

RETURNS NVARCHAR(max)
AS
BEGIN
     RETURN REPLACE(REPLACE(RTRIM(REPLACE(REPLACE(@Input,' ','¦'), @TrimChar, ' ')), ' ', @TrimChar),'¦',' ')
END

Note the dummy character '¦' (Alt+0166) cannot be present in the data (you may wish to test your input string, first, if unsure or use a different character).
