UBIK-Standard.ttf is a custom set of font icons developed primarily for use on the Xamarin Client, due to concerns over the legality of using Microsoft's Segoe MDL2 Assets icon font file on non-Windows platforms (ie. Android and iOS). Apart from this legal concern, having a standardized font icon set will contribute to having a more consistent look across the various platforms and clients as UBIK-Standard.ttf becomes more widely adopted.

The latest font set can be downloaded directly from here using the UBIK-Standard.zip file.

UBIK-Standard is an Icon Font. For Xamarin, the standard Text Font is Inter, which is included in the resources and thus available to use immediately.

UBIK-Standard is currently only supported for the Xamarin client.

Creation

The process for creating icons is documented here.

Step 01: Asset Creation

The first step is to find similar, open-source icons to tweak. Pixeden, LineIcons, or LineA, are good starting points, as they have a similar style.

When tweaking (for example, in Adobe Illustrator), use a stroke width of 3 for the base line thickness.

It is good practice to produce three sets of .SVGs; a stroke version, an expanded version, and a final version. The stroke version is more easily edited, but the lines must be 'expanded' in Illustrator to be imported as icons. Finally, duplicate the expanded version, and name it using the following syntax: 001#ubik-U0x26

• The first number is used to keep the icon list orderly.
• Add as many tags as desired using the # as separators. For example, a check mark icon may be listed as #ok#confirm#check. The - ends the tag portion of the syntax.
• The glyph code assigns the icon to a certain space on the character map. As different device vendors block different glyph code sets for different uses, it is good practice to overwrite the basic alphabet, numbers, and symbols, to ensure the icons work on a large range of devices. Starting from 21, glyph codes may use numbers, or letters from 2A (2 here being an example) to 2F.

Step 02: TTF Generation

IcoMoon is a useful online tool for generating the icon font, that can then be installed on a device or packaged into the client resources.

• Import Icons (top left) - Use this button to import an already existing font file, when creating additions, for example.
• On the Selection tab (bottom center), ensure that the desired set is fully selected, and shown with an orange outline.
• On the Generate Font tab (bottom right), double check the generated tags for the icons. The settings button beside the download button allows you to edit the font file name and version.
• The download button exports the .ttf, among other resources, in a .ZIP, that is then downloaded.

Usage

UBIK-Standard.ttf is currently only supported for the Xamarin client.

Xamarin Client

The first full version of the icon set was completed in September 2019. The tables on this page show the icons, along with a description of their intended purpose (some have multiple), and the natural language In-App Name, and Hex code suffix, both of which can be used to call the icons using XAML.

Using XAML, Glyphs can be called in two ways. One method is to use the Hex Code, and another is the In-App Name. Of these two methods, the recommended method is to use the In-App Name, as it uses a natural language attribute as opposed to a glyph code, making it more immediately apparent which icon is being requested by the code.

The two below examples show how one might use both methods to create a User symbol.

In-App Name Usage

In the below example, Glyph="{x:Static resources:UBIKIcons.User}" is used to call the User symbol.

Hex Code Usage

In the below example, the attribute Glyph= and the following Hex Code is used to call the User icon. These Hex codes can be found using a Character Map program, or by searching through the icon tables below.

Directly Accessing Icons

The icons can also be used like every other font by setting the FontFamily attribute. For example:

Icon Tables

WikiFormatting prevents the entire Hex Code from being displayed in the tables, so a space was used to break the glyph code. Please remove the space when using the Hex Codes from the table.

Known Issues

Xamarin Client

The development of the custom icon font on the Xamarin client was hampered significantly by unexpected icon substitutions, which appeared to be vendor/device-specific. To avoid this issue, the individual icons in the text file were mapped to the Hex codes used by the most basic alphabet and symbol characters.

A second issue was encountered where using unstable behavior was observed when using UBIK-Standard.ttf for icons when the user switched tabs, leaving UBIK running in the background. In these cases, circular icon containers became square when switching back to the app, and the icon glyphs were no longer visible. However, using the GlyphButton and GlyphLabel elements (as opposed to simply Button and Label) seems to prevent this issue.
