47 |
* The conversion data are in each CnvPctograph1 - 6 dll.
|
|
sl@0
|
48 |
* CnvPictographShared only to be used by ISO2022Jp.cpl, SHIFTJIS_SHARED.dll or

sl@0
|
49 |
* something. For example, when CCnvCharacterSetConverter::ConvertFromUnicode()
|
|
sl@0
|
50 |
* is called, and ConvertFromUnicode() of ISO2022Jp.cpl is called. After that,
|
|
sl@0

51 |
* ISO2022Jp.cpl sets some parameters for the conversion. At that time,
|
|
sl@0
|
52 |
* CnvPictographShared::SetCharacterSetsForPictograph() is called.
|
|
sl@0
|
53 |
