PHP rename may not be able to read Chinese filename properly, then you can do the following to convert the filenames.

before we get started, here's a bash to clean the filenames:

Bash script to replace spaces in file names

find . -depth -name '* *' \
| while IFS= read -r f ; do mv -i "$f" "$(dirname "$f")/$(basename "$f"|tr ' ' _)" ; done

This script can not work recursively.

How to rename Unicode Chinese files to Pinyin?

Posted on February 8, 2013 by hxin

I googled and found no existing tools. That’s very rare and even weird. The only useful piece of information I got was a mapping file that contains a Unicode Pinyin table. So I have to do it myself… to write a script to convert the Unicode Chinese file names to Pinyin using the mapping file.
Since I was doing Python Challenge at the time, natually I just scripted something in Python to get the job done.

The reason I did that was this. I have a HDTV that has a feature to play music from an USB drive. When I wanted to play the songs I downloaded from the Voice of China. I had a problem. The file name of the songs had many Unicode Chinese characters. The TV obviously doesn’t support Unicode. It just doesn’t display those Chinese characters at all. For example:

01 04张玮 – High歌.mp3
05 09吉克隽逸 – I Fell Good.mp3

I can only see:
01 04 – High.mp3
05 09 – I Fell Good.mp3

If those above are okay, then the following ones are ridiculous:
11 11 – .mp3
11 12 – .mp3
11 13 – .mp3
11 14 – .mp3

I have no idea what was what when I tried to choose the songs. Actually their filenames are as the following:
11 11大山 – 王妃.mp3
11 12王韵壹 – 你快乐所以我快乐.mp3
11 13金池 – 后知后觉.mp3
11 14吴莫愁 – 痒.mp3

Putting the mapping file and the script in one folder, all renaming Unicode files under a sub folder “VoC”, then just run the script. Finally I got all the file names like this, not perfect but I am able to tell what songs they are:
11 11 DaShan – WangFei.mp3
11 12 WangYunYi – NiKuaiLeSuoYiWoKuaiLe.mp3
11 13 JinChi – HouZhiHouJue.mp3
11 14 WuMoChou – Yang.mp3

I hope you find my solution helpful. Here is my Python script.

# renameCH2Pinyin.py
# Rename filename from Chinese characters to capitalized pinyin using the
# mapping file and taking out the tone numbers
 
import os
import re
 
# File uni2pinyin is a mapping from hex to Pinyin with a tone number
f = open('uni2pinyin')
wf = f.read() # read the whole mapping file
 
os.chdir('voc') # to rename all files in sub folder 'voc'
myulist = os.listdir(u'.') # read all file names in unicode mode
for x in myulist: # each file name
    filenamePY = ''
    for y in x: # each character
        if 0x4e00 <= ord(y) <= 0x9fff: # Chinese Character Unicode range
            hexCH = (hex(ord(y))[2:]).upper() # strip leading '0x' and change
                                              # to uppercase
            p = re.compile(hexCH+'\t([a-z]+)[\d]*') # define the match pattern
            mp = p.search(wf)
            filenamePY+=mp.group(1).title() # get the pinyin without the tone
                                            # number and capitalize it
        else:
            filenamePY+=y
    print x
    filename = filenamePY
    print filename
    os.rename(x, filename)
os.chdir('..') # go back to the parent folder
