FW_SetUnicode( .T. ) 2-Byte characters

[frose]

Hi,

does anyone know why these 2-byte characters "üöä", "ÄÖÜ", "ßéÉÊ" are not interpreted correctly when inserted during editing?

Code: Select all  Expand view

FUNCTION Main()

   LOCAL aArray

   HB_CDPSELECT( "UTF8" )

   FW_SetUnicode( .T. )

   aArray := { "üöä", "ÄÖÜ", "ßéÉÊ"}

   XBrowse( aArray, "Unicode 2-Byte Test - FW_SetUnicode( .T. ) - aArray",,,,, !.F., .T.,,, .F., .T. )

RETURN NIL
 

The given characters are displayed correctly:



But if you enter or edit the same characters, they will not be interpreted correctly:



What is going wrong?

This is the result with the example from https://forums.fivetechsupport.com/viewtopic.php?f=3&t=43246
when FW_SetUnicode( .t. )

Code: Select all  Expand view

local oDlg, oGet, oEdit
   local cVar1 := ""

   @ 100,20 BUTTON "CHECK" SIZE 100,40 PIXEL OF oDlg ACTION MsgInfo( "|" + cVar1 + "|" + CRLF + "|" + cVar2 + "|" )

   ACTIVATE DIALOG oDlg CENTERED
 

no words, what's going on?

cVar2 using EDIT control is correct but cVar1 using GET control is not correct?

I need to do more tests at my end.

Did you try keeping FW_SetUnicode( .f. ) // default
and try setting

Code: Select all  Expand view

  HB_LangSelect("DE")
   HB_SetCodePage("DEWIN")

Yes!

Did some more tests with ü - 0xC3BC and some other 2-byte characters:
- The first 2-byte char is ok
- all the following are not ok
- Pasting one or more 2-byte chars from the clipboard is working!

Used DE850 until now, want to use UTF-8 in the future

Used DE850 until now,

Is this working perfectly?
Can you please let me see your settings?

Yes

I do not have German keyboard, but I am using virtual touch keyboard downloaded from Google.
I noticed the same issues.
We are going to look into and solve the issue.
This may take some time.
I suggest you to postpone moving to Unicode for a few days, till we make this work perfectly.

Meanwhile you can help me by
1. Let me know if the multiline Get
@ r,c, GET ctext MEMO/TEXT ..
is working perfectly with German lang when FW_SetUnicode() is .T. ?

2. Can you paste all problem German characters here?

Good to know.

No problem, enough other problems (challenges) left when switching from xHarbour.com/DE850 to Harbour/UTF-8.

Meanwhile you can help me by

Ok, I will do.

2. Can you paste all problem German characters here?

There are only three 'German Umlaute': [/list]

üÜ
öÖ
äÄ

and the ß - UpperCase 'SS' .
For more information see https://www.berlitz.com/blog/german-umlaut-meaning-letters
In UTF-8 they are a lot of other 2-Byte characters, used in french, spanish, danish croatian, etc.
All 2-Byte characters I have tested are concerned!

One other aspects that (perhaps) fit the theme:
If you switch your windows machine to 'Beta: Use Unicode UTF-8 for worldwide language support' 2-Byte characters in the TGet() are handled differently: the first character will appear as � - https://www.compart.com/en/unicode/U+FFFD all following characters are OK!
After a while I turned the switch 'Beta: Use Unicode UTF-8 for worldwide language support' off again. There are some side effects to other applications. And in my Harbour app it's better to see the misintepreted characters e.g. ü instead off the �.
In this context this side was/is very helpful for me: https://www.i18nqa.com/debug/utf8-debug.html

Works without any objection in TMultiGet()

something else I noticed: During editing it sometimes happens that the following 2-byte characters are interpreted CORRECTLY.
So the error should be related to the length calculation of the previous characters, somewhere deep inside.

Working well with xHarbour but not with Harbour?
