Dear,
As you can see in the below image, some letters are missing in the French titles. Please fix this.
"COMMANDES AVEC R脡DUCTION"
"EXP脡DITION"
"TAXE D鈥橢XP脡DITION"

My understanding that this issue had been fixed in https://github.com/woocommerce/woocommerce/pull/26339 because I can see that everything renders as expected when testing WC 4.1 rc.3:

No, it is not fixed. At least not in wooCommerce 4.1. The missing translations (which was another problem) are now shown correctly.
This one is another issue as described in https://github.com/woocommerce/woocommerce-admin/issues/4311 (at least for the Czech and Slovak language).
This issue seems to be connected to the font used in WooCommerce Admin. It needs to support latin-extended letters/glyphs like "拧膷钮啪谩茅". Only blank spaces are where these letters should be shown. I've tested it on Czech and Slovak languages.

The problem still persists in version 4.3.1.
The Summary Numbers have been re-designed to be more akin to the rest of the WordPress core styling, and part of this move was to update the font in use here, and no longer use all capitals. As such, I feel this bug is no longer present so I'm going to close this out. If anyone on the issue thread here is still experiencing this issue with WooCommerce 4.4, please do reply back. Thanks!
@timmyc In version 4.4.1. Unfortunately the problem still persists in the Czech language.

@timmyc the same in Slovak language. There is problem with latin-extended special letters/glyphs like "拧膷钮啪谩茅". The font needs to change to support latin-ext
@timmyc Update 4.6.1- in Czech language problem solved.
@timmyc Update 4.6.1 - it's finally fixed in Slovak as well
@vvvamik and @Savi-1 thanks for confirming the fix! I'll close this out now.
