[Mono-list] conversions

[Polton, Richard (IT)]

 In fact, habing given it further thought, I have a couple of questions:

i) if I sit at a Japanese terminal (for example) and enter '-', i.e.
ichi or 'one', is this a valid Unicode character?
ii) how wide is the 'char' datatype? I assume it contains Unicode rather
than single-byte ASCII.
iii) if entering 'ichi' is valid, and char contains Unicode, then I
suspect that the below subtration will return a number substantially
greater than one.

Hi,

The code is in

mcs-1.0.1/class/Microsoft.VisualBasic/Microsoft.VisualBasic/Conversion.c
s

at line 687

The particular piece I noticed is

return Expression - '0';

Hey Richard

This is definitely odd.=20

Could you point us to the offending code or better still could you
please submit a test report in bugzilla with a test case.

Regards,
Jambunathan  K.

Hi,

I was browsing the source code for Conversions.cs (or similar) in the
VisualBasic (I think) package in 1.0.1 and came across a couple of
oddities. The one which struck me in particular was the conversion of a

single character into a numeric type. It was performed by subtracting
the absolute character '0' from the function parameter. This will only

work if the input character set is known to be ASCII or known to be
ordered in the same way? So, my question is, is it a requirement of all

.NET (and Mono) applications that the character set used is ASCII or
similar? I know the spec refers to the program as being encoded in
Unicode but I couldn't find anything regarding the recognisable input
chars.

Richard
