List of all Unicode's open/close brackets


What is a list of every Unicode bracket-like characters (including, for example: {}[]()<>)? What is a good way to search for Unicode characters?


Solution

  • There is a plain-text database of information about every Unicode character available from the Unicode Consortium; the format is described in Unicode Annex #44. The primary information is contained in UnicodeData.txt. Open and close punctuation characters are denoted with Ps (punctuation start) and Pe (punctuation end) in the General_Category field (the third field, delimited by ;). Look for those character, and you'll find what you're looking for.

    Note that not all characters that you consider brackets may be listed; for instance, quotation marks (including "«»"). are indicated with Pi and Pf (initial and final punctuation), so you might want to include those as well. And some character, like < and >, are used as brackets in some contexts (such as HTML/XML), while they are considered math symbols (Sm) in UnicodeData.txt. Those you are going to have to find by hand; there is no pre-determined listing of those.

    Here's a quick Bash script to get this information, and its output. I've included both brackets and quotes. (note: on some Bash implementations UTF-8 printing has a bug that causes it to print U+00AB "«" and U+00BB "»" as "?", and some terminals don't have the ability to render all characters correctly.)

    while IFS=';' read number name category rest
    do 
        if [[ "$category" =~ Ps|Pe|Pi|Pf ]]
        then 
            printf "%s (U+%s, %s): \u"$number"\n" "$name" "$number" "$category"
        fi
    done <UnicodeData.txt
