Change all non-ascii chars to ascii Bash Scripting - linux

Question

I am trying to write a script that take people names as an arguments and create a folder with their names. But in folder names, the non-ascii chars and whitespaces can sometimes make problem so I want to remove or change them to ascii chars.
I can remove the whitespace between name and surname but I can not figure out how can I change ş->s, ç->c, ğ->g, ı->i, ö->o.
Here is my code :
#!/bin/bash
ARRAY=("$#")
ELEMENTS=${#ARRAY[#]}
for (( i=0;i<$ELEMENTS;i++))
do #C-like for loop syntax
echo ${ARRAY[$i]} | grep "[^ ]*\b" | tr -d ' '
done
I run my script like that myscript.sh 'Çişil Aksoy' 'Cem Dalgıç'
It should change the arguments like : CisilAksoy CemDalgic
Thanks in advance
EDIT :
I found this solution, this does not look very pretty but it works.
sed 's/ş/s/gI; s/ç/c/gI; s/ü/u/gI; s/ö/o/gI; s/ı/i/gI;'
EDIT2 : SOLVED
#!/bin/bash
ARRAY=("$#")
ELEMENTS=${#ARRAY[#]}
for (( i=0;i<$ELEMENTS;i++))
do #C-like for loop syntax
v=$(echo ${ARRAY[$i]} | grep "[^ ]*\b" | tr -d ' ' | sed 's/ş/s/gI; s/ç/c/gI; s/ü/u/gI; s/ö/o/gI; s/ı/i/gI;')
mkdir $v
done

Answer 1

Anything that converts from UTF-8 to ASCII is going to be a compromise.
The iconv program does what was requested (not necessarily satisfying everyone, as in Transliterate any convertible utf8 char into ascii equivalent). Given
Çişil Aksoy' 'Cem Dalgıç
in "foo.txt", and the command
iconv -f UTF8 -t ASCII//TRANSLIT <foo.txt
that would give
Cisil Aksoy' 'Cem Dalg?c
The lynx browser has a different set of ASCII approximations. Using this command
lynx -display_charset=us-ascii -force_html -nolist -dump foo.txt
I get this result:
C,isil Aksoy' 'Cem Dalgic,

Answer 2

Simply put, you can't. ASCII only supports 128 characters.
International characters typically use some variation of Unicode, which can store a much much greater number of characters.
I think your best bet is to identify WHY your folder creation fails when using these characters. Does the method or function not support Unicode? If it does, figure out how to specify that instead of ASCII. If not, you might be stuck with sed and/or tr, which is probably not sustainable.
[UPDATED]
You should be able to substitute multiple characters via tr like follows:
echo şğıö | tr şçğıö scgio
sgio
