How to write soft hyphen?

[Juha Metsäkallas]

Say I write a word like Kraftfahrzeug and want hyphenation to happen, if necessary, between Kraft and Fahrzeug. In other words how I type html &shy or Unicode U+00AD?

And right away I figure it out at least on a MS Windows machine, alt+0173.

Or don't, and let the browser handle it based on language settings?

Except there is no single language to select.

I routinely work in an environment with operating system in one language, browers in others with variying language preferences for webpages and write texts yet in other languages. Even if the browser and the text to write happened to be in the same language, I have found that automatic hyphenation ,if even working at the first place, hyphenates wrongly.
