Hello all,
I have installed FPC on a Linux machine to find that in the
virtual terminal (true text-mode, not GUI-based emulator)
FP-IDE does not dispaly pseudographics correctly. It turned
out that changes to the SFM (Screen Font Map) doesn't have
any effect inside the IDE, and I count'd understand why.
Then, in the WIKI I found this:
On a terminal with VGA character set (currently only the
Linux console), the video unit will enable the VGA char-
acters and use them without translation.
which answered my question.
My console is in UTF8 mode, using an ISO8859-1 font, while
the FP-IDE, as it seems, is accessing pseudographics symbols
directly by glyph number (and bypassing the SFM table),
expecting them to be at locations specified in the CP437
encoding:
http://en.wikipedia.org/wiki/CP437
which means that it will only work with a CP437-encoded
font.
Why was this done and is there a workaround except re-encod-
ing the console font into CP437?
Modern FPC versions should support UTF-8 output for the IDE. I made a
patch for this, that was included in fpc 2.4.2 IIRC. Which FPC version
are you using and on which linux distro/version? What is the value of
the LANG environment variable?
