It is a common question of photoshop starters who want to include icons in such text or image files while editing. Photoshop brings a plethora of icons, emojis, and glyphs internally and offers to use them anywhere you want. Newcomers often do not find options where icons are used to stay. In Photoshop, there is a glyphs panel that contains punctuation, superscript and subscript characters, currency symbols, numbers, specialized characters, and so on. To find the glyph panels, select the Type > panels > Glyphs Panel or Window > Glyph.
Besides, you can also import colorful glyphs like emoji in SVG format. Photoshop now supports SVG fonts that provide multiple colors and gradients in a single glyph. To use SVG fonts in photoshop, you need to open the glyphs panel > select emoji once in the font list > it will show you a list of SVG fonts, double click on the item that you want to use.
