UXTERM(1) X Window System UXTERM(1)

# [NAME](#NAME)

uxterm - X terminal emulator for Unicode (UTF-8) environments

# [SYNOPSIS](#SYNOPSIS)

**uxterm** \[ *xterm-options* ]

# [DESCRIPTION](#DESCRIPTION)

**uxterm** is a wrapper around the [**xterm(1)**](/man/os/xterm/xterm.1) program that invokes the latter program with the “UXTerm” X resource class set. All arguments to **uxterm** are passed to **xterm** without processing; the **-class** and **-u8** options should not be specified because they are used by the wrapper. See the **xterm** manual page for more information on *xterm-options*.

The environment's locale settings (see “ENVIRONMENT” below) are used to discern the locale's character set. If no current locale can be determined, the locale “en\_US” (the English language as used in the territory of the United States) is assumed. The [**locale(1)**](/man/os/xterm/locale.1) utility is used to determine whether the system supports the selected locale. If it does not, **uxterm** will exit with an error and report the output of **locale**.

**Note: uxterm** may produce unexpected results if the current locale is set to one in which the UTF-8 character encoding is not supported, or if fonts using the ISO 10646-1 character set are not available. In the Debian system, the “xfonts-base” package provides the fonts that **uxterm** uses by default. To change the fonts **uxterm** uses, edit the */usr/lib/X11/app-defaults/UXTerm* file.

A similar wrapper, **[koi8rxterm(1)](/man/os/xterm/koi8rxterm.1),** is available for KOI8-R environments.

[**LC\_ALL, LC\_CTYPE, LANG**](#LC_ALL)

The values of these variables are checked, in order, to determine the character set used by the current locale.
