This error is reported for citations that use {{para|vauthors}}, {{para|veditors}}, {{para|name-list-style|vanc}}.

[[Vancouver style]] restricts author or editor names to the Latin alphabet. For the purposes of this test, [[Module:Citation/CS1]] defines the Latin alphabet as the letters defined in the [[Unicode]] Latin character sets:
: C0 Controls and Basic Latin<ref>{{cite web |title=C0 Controls and Basic Latin |website=[[Unicode]] |url=https://www.unicode.org/charts/PDF/U0000.pdf |access-date=2015-04-19}}</ref> (0041–005A, 0061–007A)
: C1 Controls and Latin-1 Supplement<ref>{{cite web |title=C1 Controls and Latin-1 Supplement |website=Unicode |url=https://www.unicode.org/charts/PDF/U0080.pdf |access-date=2015-04-19}}</ref> (00C0–00D6, 00D8–00F6, 00F8–00FF)
: Latin Extended-A<ref>{{cite web |title=Latin Extended-A |website=Unicode |url=https://www.unicode.org/charts/PDF/U0100.pdf |access-date=2015-04-19}}</ref> (0100–017F)
: Latin Extended-B<ref>{{cite web |title=Latin Extended-B |website=Unicode |url=https://www.unicode.org/charts/PDF/U0180.pdf |access-date=2015-04-19}}</ref> (0180–01BF, 01C4–024F)

This error is also reported when more than two initials are used: in case of more than two initials, list only the first two.

This error is also reported when a corporate or institutional author is listed in {{para|vauthors}} without proper delimiters.  Corporate authors should be listed this way:
: {{para|vauthors|First Surname FM, Surname AB, {{green|((}}Corporate or institutional Author{{green|))}}, Last Surname XY}}

While normally correct, sometimes the names listed on a PMID page contain errors when the author surname has a lowercase [[nobiliary particle]].  For example, {{PMID|17726700}} lists Magnus von Knebel Doeberitz as Doeberitz Mv which is not correct.  This author's name should be listed as {{para|vauthors|von Knebel Doeberitz M}}.<ref>{{cite web |title=Other surname rules |website=National Center for Biotechnology Information |date=2018-05-18 |url=https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33081/}}</ref>

Certain punctuation will be flagged as an error.  For example, Unicode U+2019, right single quotation mark, causes an error because it is not a member of the Latin character sets identified above: {{para|vauthors|Van{{red|’}}t Veer M}}.  Replace this character with the straight (or typewriter) apostrophe: {{para|vauthors|Van{{green|'}}t Veer M}}.

To resolve this error, Romanize author and editor names.<ref>{{cite book |chapter=Names in non-roman alphabets or character-based languages |title=Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers |author-last=Patrias |author-first=Karen |editor-last=Wendling |editor-first=Dan |location=Bethesda, Maryland, USA |publisher=[[National Library of Medicine]] |date=2007 |edition=2nd |chapter-url=https://www.ncbi.nlm.nih.gov/books/NBK7258/box/A48818/}}</ref>  Romanizing can result in two-letter initials, for example, the Greek letter 'Θ' Romanizes to 'Th'.<ref>{{cite web |title=Greek |website=Library of Congress |url=https://www.loc.gov/catdir/cpso/romanization/greek.pdf}}</ref> When author names have this kind of initial, Module:Citation/CS1 can't know if this kind of initial is a typo or a legitimate Romanized character so it will emit the Vancouver error.  To suppress the error after determining that the two-character initial is correct and not a typo, treat the name as if it were a corporate name by wrapping it in [[Help:Citation_Style_1#Accept-this-as-written_markup|doubled parentheses]]: {{para|vauthors|...,  Tatarinov IuS, ...}} → {{para|vauthors|...,  ((Tatarinov IuS)), ...}}

Similarly, Chinese hyphenated given names may appear in PubMed listings.  For example: 'Wang Hsien-yu' may be listed on PubMed as 'Wang Hy' which will result in a Vancouver error.  When this occurs, and upon verification that such names are correct, wrap them in doubled parentheses.
