Aspose.Font API Solution has a rich functionality to work with fonts. Conversion, glyph manipulations, loading and saving fonts, and many more. Some of the features are linked to manipulations with glyphs.

A glyph is an individually designed character of a typeface or a graphical representation of a symbol/character. To learn more about this font unit, read the Introduction to Glyph article.

We all know for sure that such fonts like Arial, Times New Roman, and Helvetica includes Latin symbols. But what about the rest of fonts? This page describes the option on how to find glyphs of the Latin symbols in the font, but the whole functionality is carefully described in the Using Glyph objects article. There you will find much more C# code examples, and learn the functionality of Aspose.Font for working with glyphs and the Aspose.Font.Glyphs namespace in particular.

To check fonts for Latin symbols we need:

  • Aspose.Font for .NET API which is a feature-rich, powerful and easy-to-use document manipulation and conversion API for C# platform.

  • Open the NuGet package manager, and search for Aspose.Font and install. You may also use the following command from the Package Manager Console.

Package Manager Console Command


    PM> Install-Package Aspose.Font

Steps to detect whether the font supports Latin symbols using C#:

  1. Specify the font that needs to be checked.
  2. Detect the Latin symbols using the functionality of the GlyphId Class.

C# Code for detecting Latin symbols in fonts

    using Aspose.Font;
    using Aspose.Font.Glyphs;
    bool latinText = true;

    //Font to check
    Font font;

    for (uint code = 65; code < 123; code++)
    {
        GlyphId gid = font.Encoding.DecodeToGid(code);
        if (gid == null || gid == GlyphUInt32Id.NotDefId)
        {
            latinText = false;
        }
    }

    if (latinText)
    {
        Console.WriteLine(string.Format("Font {0} supports latin symbols.", font.FontName));
    }
    else
    {
        Console.WriteLine(string.Format("Latin symbols are not supported by font {0}.", font.FontName));
    }
