Android Question if "M" = "M" but false, "µ".ToUpper => "M" <> "M" ?

[Hubert Brandel]

Hi,

I had some problems with a special char ... µ

sIRAblType = ... could get "M" or "µ" ... or others ...
Log("IRDA-Version JA - Typ:'" & sIRAblType & "' (1)")     ' shows 'M' or 'µ' (1)
sIRAblType = sIRAblType.Trim.ToUpperCase ' µ 0> M
Log("IRDA-Version JA - Typ:'" & sIRAblType & "' (2)")     ' shows 'M' !      (2)
Select sIRAblType
    Case "M", "µ"
         ... here I only see the original 'M' values
    Case Else
         ... here I see the original 'µ', but now 'M'
         Log("..." & sIRAblType & "' " & oIRDA.Text)  ' shows 'M' from µ records.  
End Select

some time ago, I found that in the same situation

if sIRAblType = "M" or sIRAblType="µ" then 
   ' shows TRUE when it was a M record, but 
else
   ' shows FALSE after <Trim.ToUpperCase> has changed 'µ' to 'M'
endif

after I comment out this line all works correct !
' sIRAblType = sIRAblType.Trim.ToUpperCase ' µ 0> M

very strange this ...

It may look like an 'M' but might not be.
Can you do Asc(sIRAblType) to see what code you get?

μ is greek letter, its upper case is not the latin M, but the greek Μ. Looks the same, yet their code is not.

Using Magret's StringFuction i.e. s.Trim() Command

Of course ... I thought in ANSI basic terms ... in my Windows compilers upper("µ") or ucase$("µ") will not be changed, so I was confused.
