Installation guide

DIGITAL UNIX also provides a function called fold_string_w() that

maps one Unicode string to another, performing the speciﬁed Unicode

character transformations. For more information, see fold_string_w

For more information on the Unicode support, see Unicode

G.12.3 The Worldwide Mail Handler No Longer Exists

Worldwide support subsets no longer install internationalized Mail Handler

(MH) software in the /usr/I18N/bin/mh directory. In DIGITAL UNIX

Version 4.0B, internationalization features have been merged into the

default Mail Handler (MH) whose ﬁles are located in /usr/bin/mh. Check

the value for the mhpath resource used to ﬁnd the DECwindows Mail

application. If necessary, change this value to be /usr/bin/mh.

G.12.4 Multilingual Emacs (mule)

The mule editor is a multilingual version of GNU Emacs and supports the

following kinds of characters:

• ASCII (7-bit)

• ISO Latin-1 (8-bit)

• Japanese, Chinese, and Korean (16-bit) as speciﬁed by the ISO 2022

standard and its variants (EUC, Compound Text, and so on)

• Chinese in both GB and Big 5 encodings

• Thai as speciﬁed by the TIS 620 standard

The IOSWWMULE400 subset installs Version 2.3 of the GNU mule editor and

associated software. Corresponding sources are available in the

IOSWWMULESRC400 subset.

DIGITAL UNIX does not include public domain fonts that you can use with

mule. See the mule-2.3/README.Mule ﬁle installed by the

IOSWWMULESRC400 subset to ﬁnd out how you can obtain public domain

fonts.

The DIGITAL UNIX software is enhanced with lisp libraries that support

the dechanzi codeset for Simpliﬁed Chinese and the dechanyu codeset

and tsangchi input method for Traditional Chinese. These libraries are

included in the IOSWWMULE400 subset and installed in the

/usr/i18n/mule/lib/mule/site-lisp directory.
