When we try to translate the language pack in default words you can not know if there are spaces at the beginning and end of the string.
@EnzoC @RPG-support @Maxxius @Carlos S.  @Hobbe @Teascu Dorin @Foster ....

This is where I thought to modify the table output and allow to highlight spaces.

 

find on file \applications\core\modules\admin\languages\languages.php:

			'word_custom'	=> function( $val, $row )
			{
				return \IPS\Theme::i()->getTemplate( 'customization' )->langString( $val, $row['word_key'], $row['lang_id'], $row['word_js'] );
			},

add before it

			'word_default'	=> function( $val, $row )
			{
				$val = mb_substr($val, 0, 1) === ' ' ? substr_replace($val, '<span style="background-color:#F00;">&nbsp</span>', 0, -mb_strlen($val)+1) : $val;
				$val = (mb_strlen($val) > 1 AND mb_strpos($val, ' ', mb_strlen($val)-1) !== FALSE) ? substr_replace($val,'<span style="background-color:#F00;">&nbsp</span>', -1) : $val;
				return $val;
			},

Mine is a manual change but wanted to incite the staff to integrate as soon as the functionality....

If this is not integrated soon i release a plugin.

'lang_filter_space'	=> 'CHAR_LENGTH(word_default) != CHAR_LENGTH(TRIM(word_default))'

			'word_default'	=> function( $val, $row )
			{
				$val = htmlspecialchars( $val, ENT_QUOTES | \IPS\HTMLENTITIES, 'UTF-8', FALSE );
				$val = mb_substr($val, 0, 1) === ' ' ? substr_replace($val, '<span style="background-color:#F00;">&nbsp</span>', 0, -mb_strlen($val)+1) : $val;
				$val = (mb_strlen($val) > 1 AND mb_strpos($val, ' ', mb_strlen($val)-1) !== FALSE) ? substr_replace($val,'<span style="background-color:#F00;">&nbsp</span>', -1) : $val;
				return $val;
			},

This not translate html tags on $val.
