I know that technically and are two different things, but more often than not the terms are used interchangeably (as UTF-8 is the de-facto standard Unicode file encoding). Should we merge the tags?

There's utf8x and ucs and unicode-math ... but I think it would be ok to let act as a synonym to . This way these closely related subjects could be easier found in order to answer or to look-up.

Not a single question has been tagged as too, and the other way round. That's a sign for me that they are regarded as either being interchangeably or as unrelated - the latter is not the case. A misleading consequence is that is not even mentioned in the list of related tags to , on the right sidebar, if you filter by ! And the other way round as well - as if they were totally unrelated.

To sum up, I would say: let's merge and , with as main tag because it has a broader meaning.

Update: I merged the tags and created an Unicode tag wiki.

  • I agree, but it might be nice to have some sort of no-really-utf-8 tag, too. (For instance, if someone says "I can compile my document if it's encoded in UTF-32, but if it's encoded in UTF-8, I get error blah.") I'm not sure what a good name for it would be, though.

    @Antal I don't think this is a very common use case. One could simply tag those questions with the already existing {encodings} tag. (btw @mods {encoding} should be merged into {encodings})

  • @Caramdir: I concur, that's why I'm in favor of the proposal. It's just something to think about after merging the utf-8 and unicode tags. Commented Dec 13, 2010 at 2:02
  • @Antal: I think that Caramdir's point is that tags are, by their very nature, lossy. There's no way of (and no point in) having a tagging system so that there was a perfect tag for every question. Your proposed question would fit just fine with a unicode tag, I deem.

  • @Caramdir: I merged {encoding} into {encodings}. I thought about that encoding might be a verb tag (like compiling), but I think we commonly use an encoding but don't encode by ourselves. So, the noun and thus its plural is fine.

  • As I've mentioned elsewhere on meta, I care very little about tags, but merging {utf-8} and {unicode} seems like a sensible idea to me.

  • Thank you. Could you please add LuaTeX (and maybe ConTeXt) to the tag wiki (I don't have a {unicode} bronze tag, so I cannot do it myself).

Last time I checked UTF-8: meant an encoding that depends on unicode, which implies unicode is being used or present.

but what about the poor soul who is complaining about his UTF-16 problems and has the unicode tag present

  • Erm, what about that poor soul? He'd mark it {unicode} and then hopefully specify if he meant UTF-16BE or UTF-16LE in the question.

  • I thought the question meant: should the unicode and utf8 tag be merged? if they want to talk about unicode they should add the unicode tag.

    The {utf-8} tag is now remapped to {unicode}, not the other way around. I think that should alleviate your concerns.
