This may be obvious to some, but visually-recognizing character encoding at a glance is not always obvious.

For example, pronunciation files downloaded form Forvo have the following appearance:

pronunciation_ru_оÑ‚бывание.mp3

How can we extact the actual word from this gibberish? Optimally, the filename should reflect that actual word uttered in the pronunciation file, after all.

Step 1 - Extracting the interesting bits

The gibberish begins after the pronunciation_ru_ and ends before the file extension. Any regex tool can tease that out.

I’ve written a lot about applying and removing syllabic stress marks in Russian text because I use it a lot when making Anki cards.

This iteration is a command line tool for applying the stress mark at a particular character index. The advantage of these little shell tools is that they can be composable, integrating into different tools as the need arises.

#!/usr/local/bin/zsh

while getopts i:w: flag
do
    case "${flag}" in
        i) index=${OPTARG};;
        w) word=${OPTARG};;
    esac
done

if [ $word ]; then
    temp=$word
else
    read temp
fi

outword=""
for (( i=0; i<${#temp}; i++ )); do
    thischar="${temp:$i:1}"
    if [ $i -eq $index ]; then
        thischar=$(echo $thischar | perl -C -pe 's/(.)/\1\x{301}/g;')
    fi
    outword="$outword$thischar"
done

echo $outword

We can use it in a couple different ways. For example, we can provide all of the arguments in a declarative way:
