Try to replace
var glyphIndex = (ushort)(text[n] - 29);
with
var glyphIndex = glyphTypeface.CharacterToGlyphMap[text[n]];
سؤال
I'm doing some custom controls and I have some text being drawn via Glyph Runs
My problem is that °C isn't being rendered properly by my glyphs (regardless of font family) and looks like this:
So my code (simplified) for the glyph run is:
var typeface = new Typeface(this.FontFamily, this.FontStyle, this.FontWeight, this.FontStretch);
...
GlyphRun glyphRun = CreateGlyphRun(typeface, "°C", 10, new Point(0,0));
dc.DrawGlyphRun(brush, glyphRun);
Where
internal static GlyphRun CreateGlyphRun(Typeface typeface, string text, double size, Point origin)
{
if (text.Length == 0)
return null;
GlyphTypeface glyphTypeface;
typeface.TryGetGlyphTypeface(out glyphTypeface)
var glyphIndexes = new ushort[text.Length];
var advanceWidths = new double[text.Length];
for (int n = 0; n < text.Length; n++)
{
var glyphIndex = (ushort)(text[n] - 29);
glyphIndexes[n] = glyphIndex;
advanceWidths[n] = glyphTypeface.AdvanceWidths[glyphIndex] * size;
}
var glyphRun = new GlyphRun(glyphTypeface, 0, false, size, glyphIndexes, origin, advanceWidths, null, null,
null,
null, null, null);
return glyphRun;
}
I assume its some kind of localisation issue. Any help would be appreciated.

How about using the Glyphs class
instead? The degree sign will show when using that:
<Glyphs FontUri="C:\WINDOWS\Fonts\SegoeUI.TTF" FontRenderingEmSize="80"
StyleSimulations="BoldSimulation" UnicodeString="It's 30°C"
Fill="Black" HorizontalAlignment="Center" VerticalAlignment="Center" />
