FoxTrot not indexing files containing utf16 tag [message #299] Wed, 27 May 2015 20:32 Go to next message

Hello,

We ran into a problem building an index with html files containing a utf16
tag.
The files contain the follow code in the header:



some_file.xml


If both lines and , are in the file, then FoxTrot indexes only the name of the
file and does not index their contents at all.

If we delete the UTF-16 line (), then FoxTrot starts indexing the
contents and it is possible to search inside the files.

We can not modify these files by deleting this line and it is not feasible
anyway (we have thousands of such files)/

I use Mac OS Yosemite 10.10.3, but colleagues ran into similar issue with
previous OS versions too.

I would be grateful for any insight on this problem.

FoxTrot relies on the Spotlight importers to extract indexable text from files; unfortunately, the RichText importer has some bugs or limitations concerning UTF-16 html files, and/or html files with incoherent charset tags.

If removing the charset=UTF-16 tag fixes the problem, maybe you can do a multi-file search and replace using, for example, TextWrangler?
If the files are really UTF-16, you may have ton convert them to UTF-8; TextBatchConv can do this.

Thank you very much for your reply.
Is it technically feasible to run a multi-file search and replace
on thousands of files in many different subfolders (10 Gb approximately)
with TextWrangler or bbedit. The files are actually in UTF16, so we will
also have to convert them, I will check the link you provided.

Thank you for your help.

I managed to convert a large number of our files and replace the utf16 tag
following the suggestion by FoxTrot engineering.
Thank you very much for your help.
