LyX ⇒ Hyphenation Point inside the ERT Box

[auvajs]

I have not managed to insert a hyphenation point ("Ctrl"+"-") into a word that is inside the ERT Box

Code: Select all

\usepackage{babel}
\usepackage[usenames,dvipsnames]{xcolor}
\textcolor{Plum}{NEJVYŠŠÍ}

and LyX doesn't hyphenate the word properly.

So I tried

Code: Select all

\hyphenation{NEJ-VYŠ-ŠÍ}

in the preamble but LyX probably doesn't like those characters (š) so it ended with an error:

Code: Select all

 \hyphenation{NEJ-VYŠ
                          -ŠÍ}
Hyphenation exceptions must contain only letters
and hyphens. But continue; I'll forgive and forget.

So - how to do it? I need to set-up my own hyphenation for a specific word with some punctuation characters and let it be used within a ert box...
