The commands in <#702#>ENC<#702#>|enc.def| files allow encoding-specific
commands to be defined, but they do not allow commands to be used in
other encodings. For example, the OMS encoding contains the symbol
`§', but we need to be able to use the command |§| in any encoding,
not just OMS.
To allow this, LATEX<#703#><#703#> has commands for giving default definitions
for commands, which are used when the command is not defined in the
current encoding. For example, the default encoding for |§| is OMS,
and so in an encoding (such as OT1) which does not contain |§|, the
OMS version is selected. But in an encoding (such as T1) which does
contain |§|, the version for that encoding is used.
Note these commands should not occur in
<#706#>ENC<#706#>|enc.def| files, since these should only define commands
for that encoding. They should instead be placed in packages.

|| <#708#>cmd<#708#> <#709#>definition<#709#>
This command allows an encoding-specific command to be given a default
definition. For example, the default definition for |©| is
defined be be a circled `c' with:
<#711#>tex2html_preform<#711#>verbatim71#<#713#>decl<#713#>[1994/12/01]
|| <#714#>cmd<#714#> <#715#>encoding<#715#>
|| <#716#>cmd<#716#> <#717#>encoding<#717#>
These commands allow an encoding-specific command to be given a
default encoding. For example, the default encoding for ||̈ and
|æ| is set to be OT1 by:
<#719#>tex2html_preform<#719#>verbatim72#Note that || can be used on any one-argument
encoding-specific command, not just those defined with
||. Similarly, || can be used
on any encoding-specific command with no arguments, not just those
defined with ||.
For more examples of these definitions, see |ltoutenc.dtx|.

|| <#722#>cmd<#722#> <#723#>definition<#723#>
This command is the same as ||, except that if
the command already has a default definition, then the definition is
ignored. This is useful to give `faked' definitions of symbols which may
be given `real' definitions by other packages. For example, a package
might give a fake definition of |¼| by saying:
<#725#>tex2html_preform<#725#>verbatim73#
