Bash replacement to getchar

There's a replacement in bash for getchar or get functions of C and C++?Those functions read the next char avaliable in the input stream. I've tried something like: OLD_STTY=`stty -g` stty cbreak -echo look=`dd if=/dev/tty bs=1 count=1 2>/dev/null` stty $OLD_STTY But it is not working...

set_ucodepage

set_ucodepage(3alleg4)						  Allegro manual					    set_ucodepage(3alleg4)

NAME

       set_ucodepage - Sets 8-bit to Unicode conversion tables. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void set_ucodepage(const unsigned short *table, const unsigned short *extras);

DESCRIPTION

       When  you  select the U_ASCII_CP encoding mode, a set of tables are used to convert between 8-bit characters and their Unicode equivalents.
       You can use this function to specify a custom set of mapping tables, which allows you to support different 8-bit codepages.

       The `table' parameter points to an array of 256 shorts, which contain the Unicode value for each character in your codepage.  The  `extras'
       parameter,  if  not NULL, points to a list of mapping pairs, which will be used when reducing Unicode data to your codepage. Each pair con-
       sists of a Unicode value, followed by the way it should be represented in your codepage.  The list is terminated by a zero  Unicode  value.
       This  allows  you to create a many->one mapping, where many different Unicode characters can be represented by a single codepage value (eg.
       for reducing accented vowels to 7-bit ASCII).

       Allegro will use the `table' parameter when it needs to convert an ASCII string to an Unicode string. But when Allegro converts an  Unicode
       string  to  ASCII, it will use both parameters. First, it will loop through the `table' parameter looking for an index position pointing at
       the Unicode value it is trying to convert (ie. the `table' parameter is also used for reverse matching). If that fails, the  `extras'  list
       is used. If that fails too, Allegro will put the character `^', giving up the conversion.

       Note that Allegro comes with a default `table' and `extras' parameters set internally. The default `table' will convert 8-bit characters to
       `^'.  The default `extras' list reduces Latin-1 and Extended-A characters to 7 bits in a sensible  way  (eg.  an  accented  vowel  will	be
       reduced to the same vowel without the accent).
