After day long suffer with javascript I was found completely easy solution.
I just make local copy of docsify.min.js with this patch:
var o=U(i.id||r).split('(').shift().toLowerCase().replace(/[^а-яa-z_]/g,'-').replace(/^-+|-+$/g,'')
Location (find by this part of code):
a.ignoreAllSubs=!0);var o=U(i.id||r),s=u.toURL(
I think this patch more comfortable instead worst plugins with half-working results.
Reason: Cyrillic paragraph links compatibility with GitLab markdown engine (this engine is worst too).
May be this solution will helpful for someone.
