Special characters with DrawString?!

[Jonah Olsson]

Hi guys!

I'm trying to use Swedish characters with DrawString but no luck. Do I need
to set the Charset somewhere?? I've been searching Google Groups for hours
now, but I can't find any help or tutorial. Below is my code.

Thanks for any kind of help!

Regards,
Jonah Olsson
Dim b As Bitmap = New Bitmap(1, 1)
Dim g As Graphics = Graphics.FromIm age(b)
Dim solidBrush As SolidBrush = New SolidBrush(Text Color)

Dim privateFontColl ection As PrivateFontColl ection = New
PrivateFontColl ection
privateFontColl ection.AddFontF ile(Server.MapP ath("Static/Fonts/TELEBC__.TTF"
))

Dim thisFont As FontFamily = privateFontColl ection.Families (0)
Dim regFont As Font = New Font(thisFont, FontSize, FontStyle.Bold,
GraphicsUnit.Pi xel)

Dim Width As Integer
Width = Convert.ToInt32 (g.MeasureStrin g(Text, regFont).Width)
Dim Height As Integer
Height = Convert.ToInt32 (g.MeasureStrin g(Text, regFont).Height )

b = New Bitmap(Width, Height, PixelFormat.For mat24bppRgb)

g = Graphics.FromIm age(b)

g.TextRendering Hint = TextRenderingHi nt.AntiAlias
g.SmoothingMode = SmoothingMode.A ntiAlias
g.Clear(BackCol or)
g.DrawString(Te xt, regFont, solidBrush, 0, 0,
StringFormat.Ge nericTypographi c)

Response.Conten tType = "image/gif"
b.Save(Response .OutputStream, ImageFormat.Gif )
b.Dispose()

Jonah,

It probably depends on whether the font you use is a Unicode one. If it is
not unicode, character translation should be done to match Swedich
characters stored as Unicode ones in a String with the code page the Font
uses. To set up this code page, use the GdiCharSet property of the Font
class.

Hi Dmitriy,

I solved the problem by using UrlEncode and UrlDecode, but that feels like a
bad work around. I have to call the web page (in <img src="...">) with
Web.HttpUtility .UrlEncode(...) and then decode the string in my code.

I'll try to set the GdiCharSet to see if there's a way I can skip the encode
and decode part.

Thanks.

Jonah,

Oops, I assumed you used Windows Forms. With the Web, you should set a
correct encoding for the web page in the appropriate meta tag (as well as in
the "Content-Type" header). I am not completely sure, but the HttpResponse
class should have the Encoding property. Set properly, it should
automatically take care over encoding the Unicode characters you send to the
response stream to the right code page.
