Normal spaces (U+0020) before `! ? : ; »` and after `«` are automatically converted by the parser as non-breaking spaces (U+00A0). However since a few hours, non-breaking spaces seem to be missing or misplaced when there are `<span></span>` tags:
For example on https://fr.wikipedia.org/w/index.php?title=Kiev&oldid=180348745
```
en <a href="/wiki/Ukrainien" title="Ukrainien">ukrainien</a> : <span class="lang-uk" lang="uk">Київ</span>, <i>Kyiv</i>
```
` ` should be before the semi-colon, not after.
On https://fr.wikipedia.org/w/index.php?title=Visual_novel&oldid=179960076
```
(abréviation de « <span class="lang-en" lang="en"><i>novel</i></span> »), qui consistent essentiellement en une narration et comportent très peu d'éléments interactifs et les jeux dits « AVG » ou « ADV » (respectivement « <span class="lang-en" lang="en"><i>adventure game</i></span> » et « <span class="lang-en" lang="en"><i>adventure</i></span> »)
```
` ` is missing before the closing guillemet (`»`).
