The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome.

If you want to find out how many UTF-8 bytes a letter in a PHP string has then:
ReplyDeleteprint strlen(mb_substr($string, 0, 1, "utf-8"));
strlen() returns the raw byte length, while mb_substr() returns a "character" according to the charset/encoding. In this example from position 0.
ASCII is 7 bits.
ReplyDeleteMost other languages use 8 bits (1 byte).
Many easter languages (Chinese, Japanese) use 16 bits (2 bytes).
Unicode is usually 32 bits (4 bytes).
How a character is stored and represented depends on the programming language and the platform you are using.
