to guess if your terminal supports unicode\n\n```javascript\nvar hasUnicode = require(\"has-unicode\")\n\nif (hasUnicode()) {\n  // the terminal probably has unicode support\n}\n```\n```javascript\nvar hasUnicode = require(\"has-unicode\").tryHarder\nhasUnicode(function(unicodeSupported) {\n  if (unicodeSupported) {\n    // the terminal probably has unicode support\n  }\n})\n```\n\n## Detecting Unicode\n\nWhat we actually detect is UTF-8 support, as that's what Node itself supports.\nIf you have a UTF-16 locale then you won't be detected as unicode capable.\n\n### Windows\n\nSince at least Windows 7, `cmd` and `powershell` have been unicode capable,\nbut unfortunately even then it's not guaranteed. In many localizations it\nstill uses legacy code pages and there's no facility short of running\nprograms or linking C++ that will let us detect this. As such, we\nreport any Windows installation as NOT unicode capable, and recommend\nthat you encourage your users to override this via config.\n\n### Unix Like Operating Systems\n\nWe look at the environment variables `LC_ALL`, `LC_CTYPE`, and `LANG` in\nthat order.  For `LC_ALL` and `LANG`, it looks for `.UTF-8` in the value. \nFor `LC_CTYPE` it looks to see if the value is `UTF-8`.  This is sufficient\nfor most POSIX systems.  While locale data can be put in `/etc/locale.conf`\nas well, AFAIK it's always copied into the environment.\n\n","maintainers":[{"name":"iarna","email":"me@re-becca.org"}],"time":{"modified":"2023-04-12T02:45:53.797Z","created":"2014-12-30T17:33:11.432Z","1.0.0":"2014-12-30T17:33:11.432Z","1.0.1":"2015-10-08T00:33:47.037Z","2.0.0":"2015-11-26T00:59:19.737Z","2.0.1":"2016-06-23T22:10:28.872Z"},"homepage":"https://github.com/iarna/has-unicode","keywords":["unicode","terminal"],"repository":{"type":"git","url":"git+https://github.com/iarna/has-unicode.git"},"author":{"name":"Rebecca Turner","email":"me@re-becca.org"},"bugs":{"url":"https://github.com/iarna/has-unicode/issues"},"license":"ISC","readmeFilename":"README.md","users":{"iarna":true,"flumpus-dev":true}}
