Anchor cyrillic doesnt work on modular page

Hi, I use Quark template. My default language is Ukrainian and I added the Romanian, English and Russian. When I named modular page in cyrillic then the menu anchor link doesnt work, doesn scroll to my section. In the menu, the link to the section is simply with a sign #

Try changing slugs for these sections (I assume you're talking about modular page) to all Latin chars. IIRC this is a known issue, but no one bothers to address, because there's an easy workaround

How can I make the menu names remain in Cyrillic and the anchor transition works? Yes I work with modular page (One-Page Site Quark)

@NataliaB, Maybe taking a look at frontmatter variables Menu, Title and Slug will provide some insight.

This my modular page content

title: Головна
body_classes: modular
image_align: right
media_order: hero-image.png
menu: головна

On website show menu item for this modular page in cyrillic, but scrol to section of this modular page doesnt work, beacuse after # in menu item has nothing mysite/#
If I change menu: головна to menu: home than in menu item write Home and link will be mysite/#home But I need menu item in cyrillic for my Ukrainian an Russian language version

If I add a slug then get error
title: 'Про нас'
slug: pronas

ERROR: text.html.twig template not found for page: /home/pronas

Maybe for ua and ru language version disable onpage_menu and create a menu with anchor links ? But how?

@NataliaB, you should copy/paste the modular template into your inherited theme and modify it by changing module.menu|hyphenize to module.slug|hyphenize where it can be found, but left module.menu as link text (line#32)
