I have a text box in PBI whose title is set to a measure value as shown below:

dense test = 
var seperator = "|"
var a = "some set of value:"
var a1 = 1100
var a2 = 240000
var b = "some other set of value:"
var b1 = 2300
var b2 = 15000

var alltogether = 
a & a1 & seperator & a2 & UNICHAR(10) &
b & b1 & seperator & b2 
RETURN alltogether

word wrap is off title is set to a function -> the measure value alignment = left

what I'm struggling with is I cannot get the pipe seperator to align I've tried padding with REPT() function but it seems as though the textbox decides arbitrarily how much space to add after each variable.

dense test rept = 
var seperator = "|"
var a = "some set of value:"
var a1 = 1100
var a2 = 240000
var b = "some other set of value:"
var b1 = 2300
var b2 = 15000

var alltogether = 
a & REPT(UNICHAR(127),25 - LEN(a)) & a1 & seperator & a2 & UNICHAR(10) &
b & REPT(UNICHAR(127),25 - LEN(b)) & b1 & seperator & b2 
RETURN alltogether
