Gource will not accept my .log about gource HOT 8 CLOSED

I couldn't reproduce this. What do the first few entries in that log file look 
like?

File contents are between asterisk rows.
Full file attached.

The file you attached seems to have some slightly funny character encoding 
(UTF-16?). Gource is expecting a UTF-8.

Possibly when you piped it (>) to the log file your command prompt turned it 
into UTF-16.

I am using PowerShell 4.0 (Win 8.1 x86_64).
I am not familiar with it, do you know where I van change the character 
encoding?

Did some testing, here are the results:

git log --pretty=format:user:%aN%n%ct --reverse --raw --encoding=UTF-8 
--no-renames | Out-File -Encoding Unicode log.gourcelog
> [No output, successful command]
gource log.gourcelog
> Unsupported log format (As expected, because this is UTF16, the default 
output)

git log --pretty=format:user:%aN%n%ct --reverse --raw --encoding=UTF-8 
--no-renames | Out-File -Encoding UTF8 log.gourcelog
> [No output, successful command]
gource log.gourcelog
> Unsupported log format (Huh? I thought it was expecting UTF8?)

So I decided to push on

git log --pretty=format:user:%aN%n%ct --reverse --raw --encoding=UTF-8 
--no-renames | Out-File -Encoding UTF7 log.gourcelog
> [No output, successful command]
gource log.gourcelog
> [Gource runs]

Ok what...?

If git gives it as UTF 8 and I save it as UTF 7, it runs with no problem.

It also won't work if there is a byte-order-marker (BOM) at the start of the 
file, it looks like that Out-File command line will include a BOM.

You can use 'gource --output-custom-log custom.log' to save a copy of the log 
file read by gource from git and then use that. Or use regular command prompt 
to save the git log.
