I have a store in 3 different languages, and for one of them it changes the font completely, titles, body, removes the bold. Is not an issue of the translation apps nor from Shopify, it’s about the coding. Anyone can help? I don’t know anything about coding.

Thanks

Sometime the font you’ve selected does not have some/all symbols for one of your languages.
It happens, not all fonts cover all languages.

In this case, browser uses fallback fonts and these may be noticeably different from the preferred font.

Usually, the solution is to select a different font which covers all the letters you need.
Sometimes the code change may help. For example, when using Google fonts it is possible to select which letters to include in a font file.

For better diagnosis, share a link to your store and a preview password if one is set.

Hi Tim,

I have been changing the fonts but the issue persists. This is a link of my shop, please compare the portuguese fonts with the ones in other languages.

Many thanks,

Sonia

This looks like you’ve configured your store differently for different markets.
The market selector in “Edit theme” allows you to configure versions for different markets quite differently.
