Text to string and compare to an other string

General
1

Hi guys !

got a little problem with text and strings

in my case, i have data coming from text and i need to use it / compare it with a string

case one :
Dim T as text = “bla bla” a text from parameter … normaly utf8
Dim S as string = “bla bla”

if T = S then …

it doesn’t match :frowning:

i tried to convect both of them to TextEncoding.UTF8 … same problem :frowning:

any idea ?

Maybe look in the documentation?

http://documentation.xojo.com/api/deprecated/text.html

If s.toText = t

heh strings and texts handle things differently (personally I think text gets it right)

note how they compare these two bits of UTF-8 data which on screen both show as one “character” and should compare as “the same” since they basically are the same “characters” in them

Dim s1 As String =&u00E8
Dim s2 As String = &u0065 + &U0300

If s1.LenB <> s2.LenB Then
  system.debuglog "s1.LenB <> s2.LenB"
End If

If s1.Len <> s2.Len Then
    system.debuglog "s1.Len <> s2.Len"
End If

If s1 <> s2 Then
   system.debuglog "s1 <> s2"
End If

Dim t1 As Text = &u00E8
Dim t2 As Text = &u0065 + &U0300
Dim te As Xojo.Core.TextEncoding =  Xojo.Core.TextEncoding.UTF8

If te.ConvertTextToData( t1, False ).Size <> te.ConvertTextToData( t2, False ).Size Then
  system.debuglog "t1.data <> t2.data" // not an exact replica of lenb but close enough for this
End If

If t1.Length <> t2.Length Then
     system.debuglog "t1.Length <> t2.length"
End If

If t1 <> t2 Then
     system.debuglog "t1 <> t2"
End If

Markus : it’s a little bit more complicated

Norman : i think convert to data could help, but i need to clean some “extra” character from text… it was more easy when i used string… :frowning:

i’m sending data to usb port and since i moved on Text, i got a lot to deal with :-/

fundamentally way down deep text is still just “runs of bytes” - all data in a computer is

Yeah… but few bytes are not welcome in simple ascii message in usb/bluetooth …
