[[Unicode]] would seem to offer the ultimate flexibility in producing text based art with its huge variety of characters. However, finding a suitable fixed-width font is likely to be difficult if a significant subset of Unicode is desired. (Modern UNIX-style operating systems do provide complete fixed-width Unicode fonts, e.g. for [[xterm]]. Windows has the [[Courier New]] font, which includes characters like {{nowrap|┌{{tsp}}╥{{tsp}}─{{tsp}}╨{{tsp}}┐}}♥{{hsp}}☺{{nowrap|{{tsp}}Ƹ̵̡{{tsp}}Ӝ̵̨̄{{tsp}}Ʒ}}). Also, the common practice of rendering Unicode with a mixture of variable width fonts is likely to make predictable display hard, if more than a tiny subset of Unicode is used. {{nowrap|≽<sup>ʌ</sup>ⱷ҅<sub>ᴥ</sub>ⱷ<sup>ʌ</sup>≼}} is an adequate representation of a cat's face in a font with varying character widths.

The [[combining character]]s mechanism of [[Unicode]] provides considerable ways of customizing the style, even [[obfuscation|obfuscating]] the text (e.g. via an online generator like Obfuscator,<ref>{{Cite web|url=https://obfuscator.uo1.net/|title=Online Text Obfuscator|website=obfuscator.uo1.net}}</ref> which focuses on the filters<ref>{{Cite web|url=https://stackoverflow.com/questions/3470669/should-unicode-be-allowed-in-usernames|title=web services - Should Unicode be allowed in usernames?|website=Stack Overflow}}</ref>). 'Glitcher' is one example of Unicode art, initiated in 2012: "These symbols, intruding up and down, are made by combining lots of diacritical marks. It’s a kind of art. There’s quite a lot of artists who use the Internet or specific social networks as their canvas."<ref>{{cite web|last= Zakas| first= Laimonas| title= Facebook Page Performance Art Glitchr|url= https://techcrunch.com/2012/01/11/facebook-page-performance-art-glitchr-purposefully-tries-to-activate-code-glitches/| website= TechCrunch| date = 12 January 2012|publisher= AOL| access-date = 23 June 2015|ref = Glitchr}}

With a fair compatibility, and among different online tools, Facebook symbols<ref>{{Cite web|url=https://fsymbols.com/generators/facebook-name/|title=Facebook profile name style with symbols (fb name font generator)|website=fsymbols.com}}</ref> showcases various types of Unicode art, mainly for aesthetic purpose (Ɯıḳĭƥḙȡḯả Wîkipêȡıẚ Ẉǐḳîṗȅḍȉā Ẃįḵįṗẻḑìẵ Ẉĭḵɪṕḗdïą Ẇïƙỉpểɗĭà Ẅȉḱïṕȩđĩẵ etc.). Besides, the creations can be hand-crafted (by programming), or pasted from mobile applications (e.g. the category of 'fancy text'<ref>{{Cite web|url=https://play.google.com/store/search?q=fancy+text&c=apps|title=fancy text - Android Apps on Google Play|website=play.google.com}}</ref> tools on Android). The underlying technique dates back to the old systems that incorporated [[control character]]s, though. E.g. the German composite <code>ö</code> would be imitated on [[ZX Spectrum]] by overwriting<ref>{{Cite web|url=http://www.worldofspectrum.org/ZXBasicManual/zxmanchap16.html|title=World of Spectrum - Documentation - ZX Spectrum manual - Chapter 16|website=www.worldofspectrum.org}}</ref> <code>"</code> after [[backspace]] and <code>o</code>.
