I strongly prefer human-readable anchors (when I can guess link content and realize if I have read it earlier) https://werkzeug.palletsprojects.com/en/1.0.x/tutorial/#step-0-a-basic-wsgi-introduction to codes like https://orgmode.org/worg/org-hacks.html#org98f055b I know, Cyrillic is a trivial case in comparison to your example below, however that is the case when I can confirm that result of transliteration to ASCII is usually readable enough. It is usually applied to article title to generate a path component of URL. > --8<---------------cut here---------------start------------->8--- > * こんにちは > * ｺﾝﾆﾁﾊ > --8<---------------cut here---------------end--------------->8--- Sorry, I can not estimate if the following conversion is accurate enough: python3 -c 'import unidecode; print(unidecode.unidecode("こんにちは"))' konnichiha python3 -c 'import unidecode; print(unidecode.unidecode("ｺﾝﾆﾁﾊ"))' konnitiha Hex anchors could be a fallback if smarter method could not generate something reasonable. Finally, exporters can generate compiler-like warnings if some problem with anchor stability/ambiguity is detected. A helper function may be suitable to fix ID before editing of a heading. Actually it was not obvious to me that IDs like org98f055b may be stable. It is a hidden feature. I do not know if Samuel can adjust his workflow to use copy from "published" (to local directory) files instead of copy from export buffer. I guess, as a starting point it is necessary to pre-populate cache with IDs from existing HTML documents somehow. Anyway thank you for clarifying of the role of publishing.
