German umlauts in LCase and UCase?

; Have anyone done a fast working lowercase function?

Debug LCase("ÖBB") ; does not bring up 'öbb'...

; in GFA, there UpperCase and LowerCase worked with an internal table, so even german, french and other chars from the "standard" windows set have been switched correctly...

Hmmm. In PB 3.94 all works fine. There was a bug-discussion about the 'ß' some time ago, but it was already fixed

Code: Select all

debug LCase("ÄÖÜß")
debug UCase("äöüß")
gives äöüß, ÄÖÜß (which is correct)
I don't have PB 4 here, so perhaps it is a bug in there ?

Otherwise you could use the following procedures:

Code: Select all

;- UCaseEx, LCaseEx
;- let you specify another charmap, e.g. for another language
;-
;- the char-mapping bases on hashmaps from the DataSection
;-
;- if you need other languages, please let me know, it's easy to
;- implement them using the LUCaseWrapper-tool on windows.
