How it works? 
The plugin automatically adds HTML entity <code>&nbsp;</code> ( non-breaking space ) after selected words or phrases. E.g. ‘Mr. Someone’ should be ‘Mr.<code>&nbsp;</code>Someone’. Works with:
<ul>
<li>posts</li>
<li>titles</li>
<li>pages</li>
<li>custom post types</li>
<li>comments</li>
<li>widgets</li>
<li>custom contents</li>
</ul>
You can create your own list of words/phrases or import our proposals.
Custom contents 
You can use the function <code><?php auto_nbsp($content, $echo); ?></code> to add <code>&nbsp;</code> to the custom content. Use this in your code. 
1. Param <code>$content</code> – (string) (required) Free text 
2. Param <code>$echo</code> – (bool) (optional) true (echo), false (return), Default: true
Other features: 
* Advanced Custom Fields compatibility

Zalomení is a WordPress plugin that automatically applies Czech typographic rules to post content, titles, comments, and widgets. It replaces ordinary spaces with non-breaking spaces wherever Czech typography forbids a line break, so editors don’t have to type them by hand.
Although Czech is the default, the plugin is structured around editable lists of prepositions, conjunctions, and abbreviations — so it can be adapted to Slovak (and other closely related languages) simply by adjusting those lists in the settings.
<h4>Maintainer</h4>
Zalomení is actively maintained by <a href="https://kybernaut.cz" rel="nofollow ugc">Karolína Vyskočilová</a> (WordPress.org username: <code>vyskoczilova</code>), an independent WordPress developer based in Czechia. She took the plugin over in 2026 after three years without updates, ran a full security audit, and now ships regular releases. The plugin was originally created by Honza Skýpala, whose work is gratefully acknowledged.
<h4>What the plugin handles</h4>
<ul>
<li>Prepositions — single-letter prepositions like k, s, v, z must not appear at the end of a line.</li>
<li>Conjunctions — single-letter conjunctions like a, i, o, u.</li>
<li>Abbreviations — common Czech abbreviations (e.g. např., tj., tzv.).</li>
<li>Numbers and units — prevents breaks between a number and its unit (e.g. 5 kg, 10 Kč).</li>
<li>Number formatting — keeps formatted numbers together (e.g. phone numbers like 800 123 456).</li>
<li>Ordinal numbers — prevents breaks after ordinals, especially in dates (e.g. 1. ledna).</li>
<li>Scales and ratios — keeps expressions like 1 : 50 000 on one line.</li>
<li>Custom terms — user-defined multi-word terms that should never be broken across lines.</li>
</ul>
All options are configurable under Settings → Reading. The plugin exposes a <code>zalomeni_filtry</code> filter so developers can add or remove the WordPress hooks Zalomení applies to.
