* 比較

[4] 
[[ISO/IEC 8859-9]] は [[ISO/IEC 8859-1]] の一部の文字を置き換えたものです。
互換性はありません。

[5] 
[[Windows-1254]] は [[ISO/IEC 8859-9]] の [[CR]] に独自の文字を割り当てたもので、
[[Windows-1252]] を [[ISO/IEC 8859-9]] に同期したものともいえます。
独自文字への置き換えのため厳密には [[Windows-1254]] と [[ISO/IEC 8859-9]] は互換性がありません。
文字置き換えのため [[Windows-1254]] と [[Windows-1252]]
も互換性がありません。

[7] 
[[ICU]] の 
[DFN[[CODE[ibm-5350_P100-1998]]]]
は [[Windows-1254]] です。

[8] 
[[ICU]]
の [DFN[[CODE[ibm-1254_P100-1995]]]]
は
[[Windows-1254]] の古い版で、[[ユーロ記号]]がありません。



[6] 
[[ISO/IEC 8859-3]] との関係が言われることがありますが、技術的には互換性がありません。
