I am talking about this answer. It doesn't work with XeLaTeX and LuaLaTeX, because it uses a package which is written by the PDFTeX author and is specifically for LaTeX and PDFLaTeX.
By the time I posted this comment, the answer has got 2 downvotes and zero upvotes. I can think of some possible reasons why it is downvoted:
- It does not work with XeLaTeX and LuaLaTeX.
- It does not provide a correct answer or sufficient information: the answerer should state clearly that the proposal only works with LaTeX and PDFLaTeX
For the first reason
Now: refers to a recent comment:
[...] Posting a solution that uses newer technology does not merit a downvote unless it fails to answer the question, i.e. ignoring the specified requirements. This site should encourage posting alternative solutions, some of which use LuaLaTeX or XeLaTeX. [...]
So, we should not downvote answers which don't work for some compilers except when those compilers are mandatory.
First reason is, therefore, not applicable here.
For the second reason
Okay, it is the answerer's fault. However, I edited the answers and added some information to it.
However, one must be in a very bad mood or one must be very rude to downvote such answer for such a reason. I have seen, on this site, hundreds of answers which are even less informative, they are not upvoted: okay, but they are not downvoted.
Second reason is, therefore, not probable.
So, why the downvotes? What is wrong here? And as usual, I want to add a comment:
@downvoters: Please add a comment saying what is wrong. I see no reasons.
This is some fact about the proposal: in Vietnam, in every 10 LaTeX users, 8 uses this proposal, about 1.5 uses the proposal in some documents and
babel in some other documents, only 0.5 uses
babel totally. I don't have the official satistics, but I am pretty sure this approximation is close. If TeX.SE were a Vietnamese-speaking community, the linked answer would get at least twice as many upvotes as the accepted answer.
In a TUGboat article, Hàn Thế Thành stated both answers as "correct". The proposal in the linked answer is "better for Vietnamese-only documents" and the
babel proposal is "better for multiligual documents which use Vietnamese".
