How to transform "Umlaute" (ü) to "ue" in the string?

Question

I have a string which is looking like this for example Lübeck Nürnberg Österreich with "Umlaute".

Now I want to split it and add the new "words" on the string like this Lübeck Nürnberg Österreich Luebeck Nuernberg Oesterreich.

So ä should be ae, ö should be oe and ü should be ue.

But I have no clue how to achieve this, thank you!

DATA: lt_split TYPE TABLE OF char40.

SPLIT string AT space INTO TABLE lt_split.

You can use REPLACE to replace a string with another string inside a string:

REPLACE ALL OCCURENCES OF: 'ä'
        IN string
        WITH 'ae',
        'ü'
        IN string 
        WITH 'ue'.

There is another variation of this statement, it can be used with an internal table:

REPLACE 'ä'
        IN TABLE lt_split
        WITH 'ae'.

Please note, the new string will be longer (if at least one replacement happened), this can be a problem, if the string was character type with fixed length and the new string would be longer, than allowed.
