I've edited it for you:

function wpex_excerpt( $length = 45, $readmore = false ) {
// Get global post data
global $post;
$max_characters = 40;
// Check for custom excerpt
if ( has_excerpt( $post->ID ) ) {
$output = mb_strimwidth($post->post_excerpt, 0, $max_characters, '...');
}
// No custom excerpt...so lets generate one
else {
// Redmore text
$readmore_text = get_theme_mod( 'entry_readmore_text', esc_html__( 'read more', 'today' ) );

$output = mb_strimwidth(get_the_content( '' ), 0, $max_characters, '...');
}
// No more tag defined so generate excerpt using wp_trim_words
else {
// Generate excerpt
$output_to_trim = wp_trim_words( strip_shortcodes( get_the_content( $post->ID ) ), $length );
$output = mb_strimwidth($output_to_trim, 0, $max_characters, '...');
// Add readmore to excerpt if enabled
if ( $readmore == true ) {
$output .= apply_filters( 'wpex_readmore_link', $readmore_link );
}
}
}
// Apply filters and echo
echo apply_filters( 'wpex_excerpt', $output );
}
You can change the maximum of characters in this code by changing number in $max_characters variable.
I used mb_strimwidth() function and return it to $output variable: https://secure.php.net/manual/pl/function.mb-strimwidth.php
By example you should understand what's going on:
<?php
echo mb_strimwidth("Hello World", 0, 10, "...");
// outputs Hello W...
?>
The function needs string like "Hello World", start of string (like 0), maximum number of characters (like 10) and at the end you can optionally choose nice ending of excerpt (like ...).
