I am looking for the HTML code for the X-double bar.

I know the code for a single bar:

x-bar = x̄ or x̄ (hex)

But what is it for the X-double bar?

U+0304 is the combining macron. There is a "combining double overline" at U+033F which might work for you, and a "combining double macron" at U+035E. Neither of these looks very clearly like a double bar in my browser. But if they work for you, the code would be something like ̿x which renders as ̿x or ͞x which renders as ͞x (This is HTML markup, not Unicode.) Note also that the combining character should go before the character it combines with, not after.

The accepted answer is incorrect.

U+035E COMBINING DOUBLE MACRON is meant to go over two code points. It is double only in the sense that it goes over both the code point it follows and the one it precedes, unlike normal marks that only count for the one they follow. Compare U+0360 COMBINING DOUBLE TILDE, which does the same thing. "a\x{35e}e" is a͞e, while "a\x{360}e" is a͠e.

The code point you want is U+033F COMBINING DOUBLE OVERLINE. "x\x{33f}" is x̿.

Here are all the combining macrons, using the uninames tool:

  • Actually &#x033F; is HTML syntax for a character reference referring to a Unicode character. So it's both: HTML and Unicode.
  • @Triplee. Thanks :) you saved my time
  • @Joachim: yes; I am mainly noting the terminological discrepancy in his question; after all, I was able to understand what he was asking. Also note that I expanded the answer a little bit; U+035E looks better at least in my browser.
  • @Joachim. Yes am using it for kindle which uses plain HTML
  • @triplee: You cannot put combining characters before the character they combine with: they follow it. If you write "a\x{301}b", then that acjute accent mark falls on the a not the b.
  • Those Perl one-liners only work on Unix-like systems, not Windows. On Windows " and ' are reversed - " delimits the one-liner text and it can not immediately be used inside. For instance, for the first one, perl -E "say "x\x{33f}"" results in "Bareword found where operator expected at -e line 1, near "33f" (Missing operator before f?) syntax error at -e line 1, near "33f" Execution of -e aborted due to compilation errors.". Used as is it gives: Can't find string terminator "'" anywhere before EOF at -e line 1..
