PB_Unicode string compare fails?!?!

[rchaney]

The two strings x$ and y$ SHOULD be identical, but are not is some "invisible" way!
The Unicode string is 2 bytes longer, perhaps this is the reason for the compare failure?
Debug output shows them identical!

Thanks,
Richard

Code:

Code: Select all

    x$ = StringField(ReadString(0,#PB_Unicode), #fid, fd$)
    y$ = "#Device ID"
    Debug x$
    Debug StringByteLength(x$)
    Debug y$
    Debug StringByteLength(y$)
    Trim(x$)
    Debug x$
    Debug StringByteLength(x$)

Debug Output:

#Device ID
22
#Device ID
20
#Device ID
22

Why don't you display the ASCII value of each character in the strings?

In unicode not all code point values are visible characters.

Without your file, it's hard to say. Did you check for the BOM with ReadFileFormat() ?

1. Check the string bytes

Code: Select all

ShowMemoryViewer(@x$, StringByteLength(x$))
ShowMemoryViewer(@y$, StringByteLength(y$))

2. Trim() is not used correctly

Code: Select all

;Trim(x$)
x$ = Trim(x$)
