textRange FindText

[Enes Karaca]

Hello, I am having problems with findText.

Using relatively recent build of chromium.

the chars[] in findTextFromPosition is not the same length as the text. Therefore sometimes start startPos and/or endPos is outside of the chars[] range

I am assuming iterator(created with createCharacterIterator) is skipping some chars probably around pos.nextVisible(); (searching forward) but could not get any deeper than that.

p.s this does not always happen, only in some files, i am trying to find which chars are causing problems.

here is a test page:

https://dl.dropboxusercontent.com/u/169068451/rangytest/test.html

(open console and enter searchManager.find("text") )

turns out the problem is Turkish capital letter İ (not I, it's with a dot on top)

problem with the letter is that in most languages

lowercase => uppercase

i => I

but in Turkish

i => İ(with doth)

ı(i without dot) => I(English capital i)

i assumed lowercase ı will also cause the same problem but it did not.

Any pointers how can i solve this? problem is probably somewhere around that letter, and i am guessing it's sort of a wider character than the normal characters, and converting it to lowercase in js probably produces strange stuff.

by the way it works in Firefox, not working in latest version of google chrome

It appears chrome treats İ differently than firefox, 

var str = "İİii".toLowerCase();
//str is iiii in all browsers at this point, but somehow chrome/chromium knows the first 2 are coming from İ
str.toUpperCase();

results in İİII in chromium.
but it results in IIII in other browsers.

solved by adding a line after line 1429 in textrange.js (handleMatch function inside the findTextFromPosition function )

before:

if (!isRegex && !findOptions.caseSensitive) {
  currentChar = currentChar.toLowerCase();
}

after:

if (!isRegex && !findOptions.caseSensitive) {
  if(currentChar == "İ")currentChar = "I"; 
  currentChar = currentChar.toLowerCase();
}
