Happy birthday to Lyudmila Sergeevna Belavenets!

'.. At the age of 15, Lyudmila performed the first category and has already performed in the Moscow Women's Championship. Four years later, she made her debut in the USSR women's championship, and in 1975, in Frunze, she became the USSR champion.

..

She graduated from the Physics and Mathematics Faculty of the Pedagogical Institute, but it was not mathematics that she taught, but chess. Almost half a century ago, she started working with young chess players at the Young Pioneers Stadium. The famous coach Vladimir Nikolayevich Yurkov invited her to school. Soon Lyudmila Sergeevna became not only one of the best children's coaches in our country, but also one of the most famous - after in 1974, together with Yuri Averbakh, she began to work as the host of the Chess School program on central television.

Among her students are a number of famous grandmasters: Alexey Borisovich Vyzmanavin, Andrei Sokolov, Alexander Morozevich, Grigoriy Oparin, a huge number of winners of the championships in Moscow, Russia, Europe and the world.

Lyudmila Belavenets continues to transfer her invaluable knowledge and experience in the club named after Petrosyan, in the school “Youth of Moscow”. Some of her students achieve high results in chess, someone graduates from a prestigious university and gets a useful profession. But all of them remember with great warmth the years they spent at the chess school under her tutelage.

Congratulations to Lyudmila Sergeevna on her anniversary. We wish you good health, harmony, optimism and all the best! ..'

We would like to join the congratulations.

The above example is rather bizarre though, all those extra characters for a simple em-dash?!?.

I guess I'll also never understand why the fix (or fixes) had to be separately applied to those different categories - maybe the posting stream needed different handling, but the player bios, tournament pages, and user collections are really just birds of a feather.

It's just a lament, no need to reply given the NDA constraints, though you do have my sympathy if you have to check each and every "fix" by hand.
