Could someone help me with this JavaScript, I'm trying to make an encoder but it doesn't work correctly.

Question

I'm trying to make an utf8 to ascii converter but there are a few bugs in it.
###code removed because question is answered###
1. if the same letter appears 2+ times in a string it only replaces the first one.
2. it changes the already replaced letters. example
1 = %31 but the script changes the 3 from %31 also creating %%331 and than the url isn't working anymore.

thanks for helping me.

Answer 1

1> String.replace() will replace only the first occurence by default. To replace all occurences, you must pass a regular expression at first argument, with the 'g' flag...

2> Your replacement logic fail, because in your replacement chain, you are replacing some stuff that's already a replacement stuff. To fix that, I suggest to change totally your algorithm, by iterating through the input string, and storing in another variable the result of the conversion ( so in addition, you can improve your conversion step by using a key-value object structure ^^ )...
