在Excel或者Word中插入一个文件链接，如果文件名中有空格，一切正常，但是如果文件名中有"%20"这个子串，问题就来了，Excel和Word会把"%20"替换成空格，这下反而不对了！
我试过将“%20”替换为“%2520”就像各种搜索引擎的作法一样，但是好像Excel/Word并没有象转义%20那样将%25转义为“%”字符，因此转化成URL的文件名成了abc%2520def.txt，难道Excel/Word只对%20转义，而忽略其它的HEX值？？同是Office的Outlook就正常地按照预期效果转义了。
也试过其它的转义符，如： / , // , \ , \\ ，% 等均没有效果。
为了扩大问题被解决的可能性，将问题用英文recite如下：
How to avoid the replacement of "%20" with " " in the filename linked by Excel/Word:
Given a file named "abc%20def.txt"
1、 tried to substitute "%20" with "%2520" like most search engines do, but it seems that it doesn't work in Excel/Word, 'cause the filename comes out straightly as "abc%2520def.txt", while Outlook works properly to translate "abc%2520def.txt" to "abc%20def.txt". So I'm afraid that it may be a bug of MS Excel/Word not to translate substrings prefixed with '%' except "%20", or there may be an option to be set in Excel/Word ??
2、 we tried out the possible Escape Chars including / , // , \ , \\ , % , but in vain.
Any suggestion? THX In Advance!
