Most of 9m^n (n >= 3) sets, 9m^n sets with I byte, 9m^n |
| 739 |
DRCSes do not have pseudo-UCS mapping area. It is |
| 740 |
questionable to allocate lots of code positions to these |
| 741 |
rarely-(or no-)used character sets. |
| 742 |
|
| 743 |
=item Even character sets that have pseudo-UCS mapping, some of them can't be outputed in ISO/IEC 2022. |
| 744 |
|
| 745 |
Because output of rarely-used character sets is |
| 746 |
not implemented yet. |
