Print strings with accents and special chars

[Ikerkaz]

Hi to all !!!

I have a little program that reads the contents of a folder (with _FILES$ function), then stores them in a string array, and finally it prints all the array on screen.

My problem is that I have accents and special chars on names (I am from Spain, we have Ñs and á é í ó ú).

I tried with  _UPrintString (x, y), NAME(i), , 8,font  ... but it only works with standard file names with no accents
If the name has no special chars it shows the name correctly, but with accents or Ñs it shows an empty string.

What am I doing wrong?

Thank U very much !!!

First question: Have you loaded a font with the Unicode characters in it with _LoadFont and _Font?

[Ikerkaz]

Yes, I am using Arial Narrow
Font = _LoadFont("C:\WINDOWS\FONTS\ARIALNB.TTF", 20)

Use _MapUnicode with correct data block for Spain. Press Shift +F1 in IDE then alphabetical/ _mapunicode and search your code page data block and example program.

I tested this program:

Code: (Select All)

Screen 0

Dim MyFont As Long

MyFont = _LoadFont("C:\WINDOWS\FONTS\ARIALNB.TTF", 40) 'select monospace font



Restore Microsoft_pc_cp850 'or restore single DATA field w/o field name

For ascii = 128 To 255 'assign unicode values to ascii 128 to 255 only

    Read unicode&

    If unicode& = 0 Then unicode& = 9744 'make undefined characters look like a box

    _MapUnicode unicode& To ascii 'replace ascii with unicode value

Next



Screen _NewImage(1024, 768, 32)

_PrintMode _KeepBackground

_Font MyFont



For code = 128 To 255

    Print code; Chr$(code); 'display unicode characters

Next



End



Microsoft_pc_cp850:

It shows correctly the special chars, but I don't know how to adapt it to my program
I tried to _MAPUNICODE before writing on screen my file names, but it is not working, it is showing blank strings (if the string has special chars) 

[Ikerkaz]

I've reduced my program to the bare minimum, in order to try several printing options:

Code: (Select All)

Option _Explicit



Dim As Integer Ascii, Maximo

Dim As String Archivo, Ruta

Dim As Long Unicode, Fuente



Ruta = "C:\My Program Files\Externo virtual\Test"



Screen _NewImage(640, 480, 32)



Fuente = _LoadFont("C:\WINDOWS\FONTS\ARIALNB.TTF", 40)



Restore Microsoft_pc_cp850 'or restore single DATA field w/o field name

For Ascii = 128 To 255 'assign unicode values to ascii 128 to 255 only

    Read Unicode&

    If Unicode& = 0 Then Unicode& = 9744 'make undefined characters look like a box

    _MapUnicode Unicode& To Ascii 'replace ascii with unicode value

Next



Maximo = 1

Archivo = _Files$(Ruta + "\*.*")

_Font Fuente



Cls

Color _RGB(255, 255, 255)



Do While Archivo <> ""

    Dim puntoPos As Long

    puntoPos = InStr(Archivo, ".")

    If puntoPos > 0 Then

        Dim ext As String

        ext = LCase$(Mid$(Archivo, puntoPos + 1))

        If ext = "mp4" Or ext = "avi" Or ext = "mkv" Or ext = "mov" Or ext = "wmv" Or ext = "flv" Then

            Maximo = Maximo + 1

            _UPrintString (0, Maximo * 20), Archivo, , 0, Fuente

            _UPrintString (0, Maximo * 40), Archivo, , 8, Fuente

            _PrintString (0, Maximo * 60), Archivo

            Print Archivo

        End If

    End If

    Archivo = _Files$

    _Display

Loop



End

This is my result:





But this is the original file name:

Try using the DATA values for codepage Win-1252 instead of Pc-850.

IT WORKS !!!!!!!!!!!!!!!!!
THANK YOU VERY MUCH !!!!!!!!!!!

yeah in the years this question about portability of screen output and keyboard or file input runs over and over.
Maybe it must be showed into FAQ of wiki so the solution is visible for all new users...
I remember that at the time of QB64 SDL I got the help of Clippy and then from another Czech user(sorry my bad memory doesn't let me remember his name)  that showed me how to performing  the task by using _mapunicode.
Some years after I collaborated with Steve to map keyboard input with _deviceinput(1). I got and published in that thread the set for Italian and West Europe code set.
