Incorrect Font Display

[Surasak]

I just update my program to FW24.09 (BCC7.70) , I found the Font display incorrect when I enter some of 2 THAI character font for example chr(202)+chr(161) , chr(203)+chr(162) , chr(202)+chr(164) etc. , It may be problem from unicode character, I try to use command FW_SetUnicode( .F. ) but nothing change. How can I solve this problem.

Just now tested with this program and it is working here.

Code: Select all | Expand

#include "fivewin.ch"

function Main()

   local oWnd, oGet, cText := space(20 )

   FW_SetUnicode( .T. )
   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-25
   DEFINE WINDOW oWnd 
   oWnd:SetFont( oFont )
   @ 40,20 GET oGet VAR cText SIZE 300,40 PIXEL OF oWnd
   @ 90,20 BUTTON "ฤฆต" SIZE 150,50 PIXEL OF oWnd ;
      ACTION MsgInfo( cText )
   ACTIVATE WINDOW oWnd CENTERED

return nil

Please try the above program as it is and let us know.

Also each Thai UTF8 character is represented by 3 bytes. Not 2 bytes

[Surasak]

My program is ANSI not Unicode. but some THAI characters is display like Unicode.

[nageswaragunupudi]

Did you at all try the sample we posted?

Dear K.Surasak,

Please let me see your sample code. I'm Thai. If you use Fw_setunicode(.T.), you must save your prg file as Encoding : UTF-8.
If you ANSI, don't use FW_SetUnicode(.F.) function.

My program is ANSI not Unicode. but some THAI characters is display like Unicode.

Thank you my friend Mr. Dutch.

I found the Font display incorrect when I enter some of 2 THAI character font for example chr(202)+chr(161) , chr(203)+chr(162) , chr(202)+chr(164) etc. , It may be problem from unicode character,

We have done some tests and found this problem. Is this the problem you are reporting?


Individual characters are displayed correctly, but when concatenated we see a totally different text.

We are looking into the issue.

What FWH version you were using before upgrade? This information helps us.
I tested with FWH1905 also but the behavior is the same.

[nageswaragunupudi]

It may be problem from unicode character

Yes, you are right.
These combinations are being treated as 2-byte utf8 characters.

We are looking into how to resolve the issue for you.
Please give us a little time.

Thank You So Much nageswaragunupudi,

Yes, That is my problem, It happen when enter 2 of character ascII higher than 127, But If enter 1 or more than 2 character it will not happen.
My last version is FW17 (My Program work fine with this version and older version) , I have to use QRCODE function which FW17 not support,
I also found other some problem with FW24,

for example :

- at the first time when run the program it take 5 to10 seconds before program start

- When I try to use unicode by function FW_SetUnicode( .T. ) + HB_SETCODEPAGE( "UTF8" ) and change my code to UTF8,
I found class MENU display incorrect , I test by use function GetSysFont(), It work with function msginfo() but class MENU still display wrong font

- Function msginfo() the button is not center

I do not know How to post the picture on this forums, Please told me how can I post the picture to show my problem

Dear nageswaragunupudi,

for my regular ANSI Program
? GetOEMCP(), GetACP(), HB_CDPSELECT() = 874,874,EN

? GetOEMCP(), GetACP(), HB_CDPSELECT() = 874,874,UTF8

Thank you very much for your support

Dear nageswaragunupudi,

Sorry for my fault, In case Unicode class MENU display incorrect , I found that I can assign FONT to this class to correct the font

I found some part of my Unicode program have to store space() to variable before take the value from database to variable ,
If not, GET command will cannot enter the THAI character

[Surasak]

Dear nageswaragunupudi,

As below is the sample of my Unicode Program with GET cannot enter THAI character if variable = nil at first

#include "FiveWin.ch"
function Main
local oWnd
public cFont0,oFont0,cName,oName
FW_SetUnicode( .T. )
HB_SETCODEPAGE( "UTF8" )
cFont0="Tahoma"

*cName = space(40) // FW24 Version If Without This Line, Variable cName with = nil
// I will cannot Enter THAI character
// But in FW17 Version Have no this problem

DEFINE FONT oFont0 NAME cFont0 SIZE 0,24
DEFINE WINDOW oWnd FROM 0,0 TO 12,34 TITLE "Test Program"
@ 20, 20 SAY "ENTER" OF oWnd PIXEL
@ 60, 20 GET oName VAR cName OF oWnd PIXEL SIZE 200,30
@ 100, 80 BUTTON "EXIT" OF oWnd PIXEL SIZE 70,30 ACTION oWnd:End()
SET FONT OF oWnd TO oFont0
ACTIVATE WINDOW oWnd ON INIT VarSet()
CLOSE ALL
CLEAR ALL
QUIT
return nil

Function VarSet
cName = "ทดสอบ "
oName:Refresh()
return nil
