URI Escape.osax

"URI Escape.osax" is a scripting addition to percent escape and unescape a string (especially URI).

You may have seen a string like "%E3%82%82%E3%81%97%E3%82%82%E3%81%97.png". Characters for URI (URL) are limited to subset of ascii characters, therefore other characters (ex. 2 byte characters) are expressed using "% + hex number" form. The expression "% + hex number" is called as "percent escape". "URI Escape.osax" is a scripting addition to encode strings into percent escaped form and decode it.

By the way, my English ability is very poor. I hope somebody make a correction into this document.

set escaped_text to URI Escape "あいうえお"

--> "%E3%81%82%E3%81%84%E3%81%86%E3%81%88%E3%81%8A"

log (URI Unescape escaped_text)

--> "あいうえお"

set a_uri to URI Escape "file:///Users/tkurita/ファイル.txt"

--> "file:///Users/tkurita/%E3%83%95%E3%82%A1%E3%82%A4%E3%83%AB.txt"

URI Unescape a_uri

--> "/Users/tkurita/ファイル.txt"
