C:Q1=How fileExists, inside "Lazarus"as widestring? (is main
question).

Fist. I try small read wideparamstr(1)
Second. The source of problem, is my win8English contain chinese'path,
             The fileName is englishname as "pp_ddvslide.vlax"
My project1.lpr fileexists('D:....\pp_ddvslide.vlax') result as false.
Please you can use gfnFiles *. from PBuffer.zip as optionally, or
 other function/s from Lazarus4.00

document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i

I had found that prefix '\\?\' to file name sometimes help (not only
with "max length path" limits).

Example:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   filename
:= '\\?\D:....\pp_ddvslide.vlax';
