檢視 UTF-8 的原始碼

[[分類:標準]]
===UTF-8編碼位元組含義：===
*◽◾◾◾◾◾◾◾，對於UTF-8編碼中的任意位元組B，如果B的第一位為0，則B獨立的表示一個字元(ASCII碼)；
*◾◽??????，128~191，如果B的第一位為1，第二位為0，則B為一個多位元組字元中的一個位元組(非ASCII字元)；
:識別位元固定為 128 ，表值 0~63。
*◾◾◽?????，192~223，如果B的前兩位為1，第三位為0，則B為兩個位元組表示的字元中的第一個位元組；
:識別位元固定為 192 ，(0~31)×64。
*◾◾◾◽????，224~239，如果B的前三位為1，第四位為0，則B為三個位元組表示的字元中的第一個位元組；
*◾◾◾◾◽???，240~247，如果B的前四位為1，第五位為0，則B為四個位元組表示的字元中的第一個位元組；
'''組成字'''(以「瓦」的中文 3 byte 為例)：
#第一 byte 231， 231-224=7 ，單位 4096
#第二 byte 147， 147-128=19 ，單位 64
#第三 byte 166， 166-128=38 ，單位 1
:字碼 = 7×4096+19×64+38=29926 ，字碼寫成 &amp;#29926;
