Charset aliases may be configured in Texis version 6 with an
optional charset config file, settable with the urlcp
settings
charsetconfigfromfile
or charsetconfigfromtext
(here). This allows alternate names for known charsets to be supported, or for
incorrectly-labelled charsets to be properly interpreted.
Also see the
texis.ini
setting [Texis] Charset Config (here).
