ROMAN-8 to ISO-7 Mapping 

The Best Fit mappings from the PC (or from the mainframe) to the host HP
3000 are explained in this section, along with problems which may arise
in such mappings.


NOTE  Characters not mentioned in the following discussion are mapped
      exactly to themselves.  For example, Z always maps to Z.


Uniform Mappings 

Fifty-six characters always map to the same new character, regardless of
which of the nine ISO-7 character sets you've specified.

   *   Thirty-eight of them are alphabetic characters with diacritical
       markings (accent, circumflex, cedilla, and so forth).  These
       typically lose the diacritical marking during the mapping.

   *   Eighteen additional characters map to characters which are close
       in appearance or function.

Dropped Diacritical Markings.   

As a general rule, alphabetic characters which have diacritical markings
are mapped to the same characters without the marking.  The following
figure shows a few examples:

Other Uniform Mappings.   

Characters in the following figure always map to the same new character:

Variant Mappings 

There are thirty-nine characters which map differently depending on which
ISO-7 character set has been specified.  The following three-part figure
illustrates these mappings.

In the figure, SS stands for SVENSK/SUOMI, DN for DANSK/NORSK, F for
FRANCAIS, FM for FRANCAIS MUTE, D for DEUTSCH, UK for UK, E for ESPANOL,
EM for ESPANOL MUTE, and I for ITALIANA.
