#2016 new defect

GUI: non-english chars in directory names not supported

Reported by: SF/clemty Owned by:

Description

German users have the directory "Startmenü" (start
menu) on their system, ScummVM displays the umlaut ü
garbled - possibly because no character for that
exists, so it just loads random stuff from that memory
position.

While this display oddity is surely just a minor
annoyance I think it *might* cause problems if you read
random data - maybe some really smart OS would detect
that as buffer/security problem?

Workaround might be to check for every value >max
supported character and replace it by _ or ? or similar
in display (not the string itself, or we can't access
those dirs anymore :-)

Known issue, and it's more complex than that: the drawing
issue is only the tip of the iceberg. Our config file is
ASCII, and path names in many modern operating / file
systems use unicode (UTF8) for filenames, so you may not
even be able to specify the path properly in the config file
(well, using UTF8, it *should* be possible to use a UTF8
text editor to modify the config file accordingly, but the
GUI won't be able to properly render those paths.

Of course, it still would probably be a good idea to define
a special symbol which is drawn whenever a glyph is not
present in a given font.

Over here, no garbage is drawn. And in fact, our font
renderer already contains checks, chars which are not
supported by the font currently are mapped to the space
character (I guess mapping them to a special symbol instead
might be better).

In my case, the OS gives us UTF8 encoded chars, so the ''
is indeed mapped to two bytes in the string; and those two
bytes, by chance, happen to be in the range of chars our
default font supports, so the '' is drawn as 'u' over
here. Annoying but harmless.

This held true for the legacy GUI but v1.5.0 introduced support for TTF fonts so I think this is no longer relevant for ports which take advance of this (?).

Which ports still use the old font?

comment:8 by sev-, 21 months ago

It is not about drawing, but also how we deal with strings internally. The required amount of changes is relatively big.

comment:9 by bonki, 21 months ago

I understand that this is about internally handling UTF8-encoded strings (which I gather we don't do) but I just tested this on Windows 10 and it "just works". I can add games in folders containing umlauts, the paths are printed correctly in all parts of the GUI and I can launch the games without problems, even though scummvm.ini itself is not UTF8-encoded.

(I'm not saying that this is ideal, just that the symptoms don't seem to show anymore when FreeType2 is enabled)
