Composed characters

I’ve noticed that there’s a way of depicting stress signs in Cyrillic text, like the following: КМІТЛИ́ВИЙ, ТЯМУ́ЩИЙ, МЕТИКО́ВАНИЙ, МЕТИКУВА́ТИЙ, ПОКМІ́ТЛИВИЙ, ШТУДЕ́РНИЙ. I don’t know how they were typed. But analysis revealed that they refer to so-called composed utf-8 characters. On the way of the investigation it appeared that the XOrg allows to define a custom composition key to type complicated characters easily.

There follow few examples below:

<rctrl>=e ⇒ €

<rctrl>--- ⇒ —

<rctrl>'e ⇒ é

<rctrl>~n ⇒ ñ

Nice! So I know how to type diacrytic characters in any graphical application. Additionally, to the graphical stress sign is one of composed unicode characters, it can be inserted into an XML by its code: ́. There’re many other composing characters, which can do interesting things: w̳o̸rld.
